I believe that you must have heard or had an EKG done. Whether in a hospital or cardiology clinic, the electrocardiogram is a routine examination.
Though familiar with the term EKG, most people know little about it. One of my friends even told me, “when doing an EKG test, I worry about getting an electrical shock! Every time when I am going to do a 12-lead EKG, I feel nervous.” Actually, EKG is a safe, non-invasive, painless test and has no major risks.
As EKG is the most common physical examination, there are some basic facts that you have to know, so that you will not be nervous when doing the EKG test, or feel confused after reading the EKG results.
What does an EKG monitor do to your heart?
An EKG is used to record the heart’s own electrical activity instead of discharging to the heart.
The beating of the heart is directed by its own electrical signals. The electrocardiogram machine can record these signals and show them through curves.
If there is a problem with the heart, the electrical signal of the heart will be abnormal, and the EKG curve will be different. Through the EKG graph, doctors can see if there is a problem with the patient’s heart.
EKG tests do not cause damage to the heart. It’s just a recording device, so you don’t have to be nervous when you’re doing an EKG.
Is it necessary to make EKG a part of a routine physical exam?
Commonly, many institutions take EKG as a routine physical exam. EKG tests are always used to screen for heart disease.
These people must do the electrocardiogram test:
Persons over 60 years of age;
People with risk factors of cardiovascular disease such as hypertension, diabetes and hyperlipidemia;
The risk of heart disease in these groups of people is much higher than in others. So it is necessary to carry out EKG examinations regularly.
The electrical signal of the heart is very complicated. It is difficult for people who are not cardiologists to thoroughly understand the EKG. So it is best to consult a cardiologist to interpret the EKG if you are in doubt about the EKG results.
In general, words in EKG reports like “sinus rhythm” and “sinus arrhythmia” mean a relatively normal situation.
There are abnormal EKG examples like “conduction block” “myocardial infarction” “tachycardia” and “bradycardia”. If you experience those EKG events, you need to go to seek emergency medical attention.
What does the word “sinus rhythm” of an EKG report mean?
Some electrocardiogram reports have a lot of confusing technical terms.
For example, in many reports, the first sentence is “sinus rhythm”. Many people don’t know what it means.
As a matter of fact, “sinus rhythm” is the signal of heartbeat. “Sinus” refers to an anatomical structure of the heart called the sinoatrial node.
The heart must start beating from the sinoatrial node, or it is an abnormality or disease.
Some friends have this kind of experience: the heart is uncomfortable, but the EKG result is normal. Why is that?
The electrocardiogram is a tool to analyze the electrical activity of the heart, but it only reflects one aspect of the heart. There is a metaphor circulating among doctors that vividly explains the function of various cardiac tests as here:
If you think of the heart as a house:
The echocardiogram is used to see how many rooms the house has, and if the wall of the house is good;
The electrocardiogram is used to see whether the circuit is normal;
The coronary angiogram is used to see if the pipes in the house are blocked or leaking.
We can see that only when the abnormal electrical activities of the heart occur, the electrocardiogram will be abnormal.
Several reasons why your heart feels uncomfortable but your ECG is fine
There may be several reasons why your heart feels uncomfortable but your ECG is fine:
The monitoring time is not enough
People may be only hooked up to the machine for a very brief amount of time, so heart rhythm irregularities are not shown in the EKG waveform. Thus the doctor will suggest the patient to continuously monitor their hearts for over 24 hours.
2. It’s not a heart problem
“Heart is not comfortable” is a very subjective feeling. Having this feeling does not necessarily mean heart problems. It may be temporary emotional distress or stomach disease. The stomach and heart are close together, so it’s easy to get confused. Sometimes the doctor will also ask patients with stomachache to do an electrocardiogram.
3. It’s too mild
When the heart abnormality is so mild that it is not recognized by an EKG, other tests may be needed.
4. It’s too severe
Sometimes heart disease is so serious that the electrocardiogram judgment is “false negatives” (where the test fails to identify a real problem), which is related to the principle of the electrocardiogram. Doctors will make a comprehensive judgment based on the patient’s physical condition, and the results of the ultrasound, chest X-ray and other heart examinations.
Any factor can cause the narrowing of the airway, and the upper airway obstruction may cause nocturnal hypoxia during sleep, leading to sleep apnea syndrome. The main common causes are:
The prevalence of OSA (obstructive sleep apnea) increases with age from young adulthood through the age of 60s and 70s, then appears to plateau.
The OSA is two to three times more common in men than in women. But between men and the peri- and post-menopausal women, the gender difference in prevalence is not as great.
For both men and women, the prevalence of OSA increases with increasing BMI and some weight-related indicators such as neck circumference, waist-to-hip ratio. Studies have found that a 10% weight gain can increase the risk of developing OSA by 6 times.
Upper airway structure abnormalities:
The obstruction of the upper airway (oral cavity, nasal cavity, and pharynx) caused by various reasons, including nasal diseases/nasal congestion such as deviated or crooked nasal septum, turbinate hypertrophy, sinus polyps, etc., oral and pharyngeal factors such as tonsil and adenoid hypertrophy, an overly long or floppy soft palate, elongated uvula, swollen tongue, the back of the tongue base, etc., craniofacial abnormalities such as the smaller-than-normal lower jaw, and upper airway narrowing caused by other reasons such as infection, trauma or surgery, etc.
Drinking alcohol or using sedative-hypnotic drugs:
These substances can make the soft tissues of the upper airway more flaccid, which will obstruct the airflow, make breathing more difficult, cause sleep apnea, and prolong the duration of apnea.
Smoking may increase the risk of developing OSA, or at least worsen existing symptoms. In one study, current smokers were three times more likely to have OSA than those who had smoked in the past (but had quit) or who had never smoked.
Other diseases causing sleep apnea syndrome:
cerebrovascular disease, congestive heart failure, hypothyroidism, acromegaly, vocal fold paralysis, brain tumors, neuromuscular disorders, laryngopharyngeal reflux, gastroesophageal reflux, and airway compression due to mediastinal mass. These diseases mentioned above can cause or aggravate airway resistance, thus causing sleep apnea.
Other medical conditions that may have an increased association with OSA include obesity hypoventilation syndrome, hypertension (particularly resistant hypertension), cardiovascular disease, atrial fibrillation, pulmonary hypertension, end-stage kidney disease, chronic lung disease, including asthma, chronic obstructive pulmonary disease (COPD), and idiopathic, pulmonary fibrosis; stroke and transient ischemic attacks, pregnancy ( gestational diabetes, pregnancy-induced hypertension), acromegaly, hypothyroidism, polycystic ovary syndrome, Parkinson’s disease, floppy eyelid syndrome.
Who is most affected by sleep apnea?
Sleep apnea syndrome is most common in people who are obese, especially those who are centripetally obese with thicker necks and larger hips.
Men are more likely to develop OSA than women.
People who are older are also more likely to have OSA.
In terms of facial appearance, people with small mouths and small lower jaws are more likely to develop OSA.
People who smoke or drink alcohol for a long time or take sedative drugs before bedtime are also at high risk for OSA.
In addition, there is a certain degree of familial aggregation of OSA, which may be related to genetic factors and common lifestyle habits. For example, genetic factors may make most of the family have small mouths and jaws, or common lifestyle habits make more overweight people in the family, etc.
Furthermore, the development of OSA is associated with the onset of certain specific medical conditions, such as women who are pregnant are more likely to develop OSA than women who are not pregnant; and menopausal women are at greater risk of developing OSA compared to premenopausal women.
What are the conditions that predispose to sleep apnea syndrome?
Sleeping in the supine position, drinking alcohol, or using sedative-hypnotic drugs before bedtime can significantly increase the risk of apnea during sleep that night, and worsen existing OSA symptoms.
Monitoring ECG with smartwatches is becoming increasingly common. Apple, Fitbit, and a number of other brands have come out with solutions. What these have in common is that they are on-demand, work from the wrist and typically capture a reading lasting around 30 seconds. Wellue Heart Health Monitor is something much more sophisticated.
This is the type of device that was previously only available in hospital settings. It offers 24-hour monitoring of ECG and provides analysis of up to 14 different kinds of abnormal heart events. The device is non-invasive and completely safe to use.
The procedure is simple and consists of sticking two electrodes onto the skin on your chest. You can do this with a chest strap or patches.
In private hospital settings, a single session with a 24-hour ECG monitor can set you back upwards of between $150 and $200. Wellue’s device comes with a one-off $299 price tag. There are no subscription fees or other expenses and more than one person can use it. You can check it out on getwellue.com .
The company sells a range of other products. Our review of its O2Ring can be found on this link. That one is primarily designed for people who need to track their oxygen levels in detail, especially those who have or suspect they have sleep apnea or another medical problem. Wellue even sells a couple of wireless portable ultrasound devices allowing you to image a full human body!
Over the past few weeks, I’ve tested the Heart Health Monitor in a number of different use scenarios and with different people. Here’s what I made of it.
Wellue Heart Health Monitor review: Design & hardware
Single-lead ECG monitor
Looks and feels like a standard heart chest strap
Records for up to 24 hours
Three-day battery life on a single charge
Look & feel
In the box, the Heart Health Monitor comes with the main unit, a power/data cable for charging and uploading data, a little USB drive with the analysis software, a pack of disposable electrode patches, and a chest strap. As far as the USB drive, you don’t really need it. It contains the PC version of the software, but you can also download this from Wellue’s website along with the Mac equivalent. Also, downloading directly from the website will ensure you have the latest version which is better.
The EKG monitor looks well made. it has a rubbery feel to it and the middle part bends. This is so that it contours better against your chest. The size of the main unit is 100 x 23 x 8.3mm and it is extremely lightweight (1.23 oz with the battery). Once positioned on your chest, you really don’t feel like you are wearing it. If you’re a runner and have worn a heart rate chest strap – this is exactly the same.
There is no display or “On” button. When you attach the main unit to the electrodes it will automatically start recording and end when you remove it. Rather annoyingly, there is also no “Off” switch. So it is a bit like a television set that is on standby – a little LED light will flash every few seconds even when the device is not used. Which to me seems like a waste of battery life. Surely it would not have been that difficult adding a little “Off” button.
Moving quickly on to water resistance which comes in at a rating of IP22. Meaning, the Heart Health Monitor is “protected against insertion of fingers” and can withstand “vertically or nearly vertically dripping water”. So it is not water-proof.
Not surprising as I cannot really see a scenario when you would need to wear it in water. This is a general health monitor, not a sports tracking device. Having said that, you can wear it while exercising.
All in all, the design gets a thumbs up from me. The monitor is comfortable to wear, feels quality made and is small enough to carry around with you with ease. Plus there’s no power-hungry display.
The device is much more convenient that a hospital ECG Holter monitor which is bulky, with wires and 5-7 electrodes that need to be attached to the chest. My only wish would be for a way to entirely switch the thing off.
Under the hood
Wellue Heart Health Monitor is a single lead ECG reader. It can record up to 360,000 ECG/EKG signals in a day, intelligently identifying a bunch of different heart arrhythmia risks. According to the company’s website, its analysis system is based on 300,000 patients and 50 million learning data points.
As far as memory, you can store 10 individual ECG sessions on it or 30 hours of data. The maximum session you can record is 24 hours. To make space, once the memory is full it will start overwriting the old data. But because you are meant to use PC or Mac software, your historical data sits on your computer’s hard disk. Which makes your session logs limitless.
Fully charged, the Heart Health Monitor can keep going for 72 hours. Wellue says you can refuel it up 300 times before performance will start to become degraded. A battery replacement possibility would be a plus. Having said that, with normal use the Heart Health Monitor should be good for a few years before it starts to see battery degradation.
To refuel simply plug one end of the proprietary cable into the monitor and the other end into any standard USB outlet. When the LED light turns from reddish to green, you’ll know the battery is on max capacity. This does not take long.

Wellue Heart Health Monitor review: Functionality
Use with the chest strap or stick-on patches
Picks up on 14 different ECG abnormalities
No Bluetooth or WiFi is required
Excellent PC and Mac software
Smartphone app of limited use
Setup and first use
A highlight of this product for me is the ease of use. Simply tighten the strap around your chest and attach the main unit to the pins – the end with the letter R needs to go on the right side. A little vibration along with the blinking green light will let you know that it has started recording. Prior to that you’ll want to wet the plastic strip on the inside of the strap a little. This is to ensure a good signal is captured right from the outset.
The other option is to use the patches provided to secure the device to your chest. Just ensure that they are positioned at a 45-degree angle. These are single-use, disposable patches and your purchase gets you 10 in a box. You also have the option of obtaining a box of additional patches – a pack of 60 costs $29.
I tried both ways of wearing it and must say that I prefer the chest strap. It is easier to put on and take off. Once it is attached to the chest, you don’t feel anything anymore and it doesn’t bother you at all.
And while it might not feel as secure while you are sleeping, in the end I found it captured uninterrupted sessions most of the time. With typical tossing and turning there’s the potential to bump the main unit. This starts a new session each time. I found that while this typically did not happen to me with the chest strap option, it did at times with the patches. Plus, when you remove the stickers they leave a red mark on your skin and it takes about a day before the rash disappears.
You’ll be happy to know that nothing is transmitted to the outside world, so no Bluetooth or WiFi is required. And the device will keep recording your signal continuously until you remove it.
Another option, which I didn’t really find all that useful, is to rest your fingers on the electrodes. This is meant for a quick check and works with the smartphone app. But the signal quality is not as good so I found that to be of limited use.
The smartphone app shows a live feed of ECG & heart rate
The Heart Health Monitor comes with computer and smartphone software to help you screen for heart problems. Starting off with the weaker part of the system – the iOS and Android smartphone app.
Like some other Wellue products, you are meant to use the ViHealth app. Pair your Heart Health Monitor to the smartphone, attach it to your chest and it will automatically start to stream data to the smartphone display.
Below the real-time data of your heart rate and electrocardiogram session curve, you’ll see a little “Record ECG” button. This allows you to capture and save details of your session. The max recording time is 30 minutes.
You also have the option of going into a history log and reviewing any individual recordings. Plus you can export the ECG readings in PDF format. But this is where the functionality ends. No analysis is provided so you are left on your own to draw conclusions.
The PC, MAC software makes this product what it is
The smartphone app can be useful for a quick checkup but is of limited use as it lacks the deep AI analysis of the PC and Mac software. Which is the part of the system which makes this product what it is. After all, ECG recordings without analysis are of limited use.
The way this works is that you download and install the software on your computer. Then each time you connect the Heart Health Monitor to your computer (via the USB power cable), you’ll have the option to download recently captured ECG data. This is submitted to the cloud for analysis and 20-30 minutes later a report will be ready with your results. Motion artifacts are filtered out in the analysis.
When you think about it, in a full day the device captures hundreds of thousands of data points that would be impossible to evaluate as a whole manually. So the AI part is an absolute necessity.
As mentioned, the device and AI ECG algorithm can pick up on many different events. This includes Sinus Rhythm, Ectopic Rhythm, Sinus Tachycardia, Sinus Bradycardia, PAC (Premature Supraventricular Contraction), PVC (Premature Ventricular Contraction), Couplet of PAC, Couplet of PVC, PAC Bigeminy, PVC Bigeminy, PAC Trigeminy, PVC Trigeminy, Supraventricular Tachycardia, Ventricular Tachycardia, Atrial Flutter, Atrial Fibrillation and heart rate variability (HRV).
The report is in an easy-to-digest format. It flags up irregularities in the ECG in a summary format along with conclusions. You can jump to the exact spot in the ECG where a disordered heartbeat occurred via the navigation panel on the left.
The software also lists hourly data in table format quantifying when and where something was found along with the number of events. Of course, you also get the actual ECG waveform. All of this can be exported in PDF format and shared with the doctor or loved ones.
There really is lots of info to sink your teeth into. However, something on my wish list would be more detailed explanations. We are not all qualified doctors so you end up Googling to understand some of the terms. But don’t be surprised if you do find some sort of abnormality. A prolonged test is bound to pick up on at least something minor. That’s normal.
Routine ECG/EKG checkups at your doctors typically take a few minutes. This can make it difficult to pick up on heart problems. After all, ECG events can be of sporadic and transient in nature. Hence the benefit of longer readings and the usefulness of this device.
Quality of data
As far as the quality of data, I can vouch that the heart rate information is accurate and that the device delivers a stable quality the recordings. The accuracy of ECG and analysis by AI, on other hand, you have to trust. There’s no way for me to perfectly assess this accuracy.
In my case, I tried it out in various use scenarios. For the most part, it found nothing wrong, only picking up on minor issues. Which is what I’d expect. Here’s an example of my results from a 9-hour monitoring session.
This is the detailed five-page report. Click on the thumb to open.
I also lent the device to a person with a known ECG abnormality – Afib, taking medication for the condition. And during five and a half-hour recording sessions, the Heart Health Monitor identified, logged, and charted a total of 632 instances of Afib. That’s how detailed the data gets!
Here’s the full report.
Also worth a mention are studies on Wellue’s website illustrating the suitability of using a single-lead ECG recorder for detecting cardiac arrhythmias in patients referred for dynamic ECG monitoring. You can read more on this link.
Wellue Heart Health Monitor review: The bottom line, is it worth it?
Wellue Heart Health Monitor is a clever little device that provides similar information to a traditional Holter Monitor. But it is easier to use and less costly. It allows you to do tests at your convenience without having to schedule doctor appointments. A way to conduct a preliminary analysis of arrhythmia and other heart abnormalities from the comfort of your home.
The device itself is very lightweight and offers a couple of ways of attaching to your chest. Once positioned, you really don’t feel like you are wearing it.
A highlight of this product is the PC and Mac software. The AI ECG analysis provides a wealth of info on your heart health including cardiac activity (heart rate, rhythm disturbances, HRV parameters), along with details of all individual irregularities. The signal form of a single-channel ECG is recorded in full. Of course, the accuracy is never going to be as high as a clinical-grade device but suffices for the purpose. Wellue also sells a 12-Lead Holter Monitor (use coupon GW10 for a 10% discount), which has medical-grade accuracy and works with the AI Analysis.
And while the PC and Mac software is quite good, the smartphone app is pretty barebones. Perhaps something that will be upgraded with future software updates.
Is Wellue Heart Health Monitor really something a person with no known heart issues needs? Perhaps not. But I would recommend it to those that have pre-existing conditions or those that want an additional way to keep tabs on their family’s health.
Finally, it is worth pointing out that this is not a medical device and is not meant to replace clinical Holter monitoring. Look at it as a convenient way to record your heart rhythm for prolonged periods and identify potential conditions – any time you feel the need to.
Poor sleep may cause high blood pressure? Some researchers report that poor sleep has become a risk factor for hypertension in the group of young and middled-aged people.
1. Insufficient sleep or excessive sleep
There is a U-shape curve relationship between sleep duration and high blooe pressure, which means sleeping for not-enough time or too much will increase the risk of developing hypertension. It is suggested to sleep for 7 or 8 hours for adults.
Previous studies have showed that people aged 32 to 59 who averaged less than 6 hours of sleep were more than twice as likely to develop hypertension as those who have enough sleep time. Those who sleep less than 4.9 hours have 3.15 times of the risk of developing hypertension.
Why does lack of sleep affect our blood pressure?
When our sleep time is reduced, the waking time is relatively prolonged, the excitability on the heart influenced by the sympathetic nerve system is strengthened, which will activate the hypothalamic-pituitary-adrenal axis, promoting a series of hormones secretion, then resulting in increased blood pressure.
In addition, hypertension can also affect sleep, causing autonomic dysfunction, resulting in a significant decline in sleep quality. Eventually, there is a vicious cycle between sleep deprivation and high blood pressure.
Mild snoring has little impact on health, but severe snoring with apnea, known medically as obstructive sleep apnea (OSA), is a cause for alarm.
Studies have shown that about 50% – 92% of OSA patients have hypertension, and 30% – 50% of hypertension patients have OSA. Excluding the influence of obesity and age, OSA has become an independent risk factor for hypertension.
Why does snoring affect our hypertension?
OSA patients are prone to apnea during sleep, which leads to intermittent hypoxia. The transition from hypoxia to resuming breathing increases the activity of sympathetic nerves, causing peripheral vascular contraction.
In addition, the impaired endothelial function of resistence vessels will affect their diastolic function, resulting in vasoconstriction and increased blood pressure. Studies have shown that endothelium – dependent dilation of resistance vessels is impaired in OSA patients compared with healthy people.
The American Heart Association BP measurement guideline stated that 3 readings should be taken in succession, separated by at least 1 min. The average value of 3 bp measurements should be used as the more accurate and reliable blood pressure readings.
This wifi blood pressure monitor is perfect for you to continuously measure 3 times of blood pressure to prevent from giving you a false sense of security about your health.
In addition, this monitor can track ECG for 30s and the connected APP will offer AI Analysis to detect some ECG events. Data can be conveniently synced through both of Wi-Fi and Bluetooth.
According to the American Sleep Association, the repetitive breathing pauses caused by sleep apnea during the nights can occur several times per hour and last for over 10 seconds. Continuous trackers like Checkme™ O2 Max supports long hours monitoring during your sleep, can help detecting all the Apneic events and Hypopenic events in every 2 seconds.
The iBreeze makes it easier than ever for new CPAP patients to adjust to therapy. The smart technology of the iBreeze also helps make humidification more dynamic, helps prevent leaks, and also captures critical sleep data for you and your doctor to have and review anytime.
This machine is the ideal choice for patients who have difficulty adjusting to CPAP machines.
An ECG or an EKG – it’s an electrocardiogram. It shows you the electrical activity of the heart. But how do you do one at home? I’m going to show you how to do a 24-hour EKG at home using this little device, the Wellue 24 Hour ECG Recorder.
About the ECG
As the electrical signal travels through the heart, that signal can be recorded using an ECG – an electrocardiogram. An ECG has different parts:
The P wave – this shows the depolarization of the atria
The QRS complex/interval – this shows the depolarization of the ventricles
The T wave – This shows the repolarization of the ventricles.
The ECG gives you an idea of how well the heart is functioning and can cue you in when there are issues like atrial fibrillation, heart defects, abnormal heart rhythms or arrhythmias, and a bunch of other cardiovascular issues.
There are all kinds of devices that can be used to take an ECG at home. In fact, my watch even does an ECG. But in order to get a full picture of your heart function, a doctor might order you to wear a Holter monitor.
A traditional Holter monitor is a device that you might put in your pocket or attach to your belt. It usually has 5 leads that attach to sticky pads that are attached to your thoracic region in different places. But the folks over at Wellue have sent me over a different kind of 24-hour ECG monitor that has some really cool features.
The Wellue 24 Hour ECG Recorder
This 24-hour ECG recorder is a relatively small device. There are two ways to wear it and get recordings.
Using a Chest Strap
It comes with a detachable strap that you can use to strap it around your chest. This method is the easiest. However, when I did it this way, it didn’t work very well for me. Evidently, I move around during my sleep and when I looked at the ECG report that I got after using it that first night, there was a lot of crazy stuff going on. There were times when I was moving around like crazy and it messed up the signal.
Using Disposable Electrodes
It comes with disposable electrodes that you can use to stick the device directly onto your chest. They are VERY sticky and once you put them on and won’t move. Personally, this is the method I recommend because you get more reliable results. Once you attach it to your chest, it’ll just start monitoring your ECG.
Unique Feature: ECG Recorder with AI Analysis
Once you’ve collected data by wearing the device, you can connect it here to your computer using the provided USB cable and import the results. It then uses AI to analyze your ECG report giving a preliminary diagnosis. It’ll let you know if it detected any atrial fibrillation or abnormal heartbeats. It’ll alert you of any tachycardia or other arrhythmias.
You should still follow up with a medical professional if you’re noticing any potential problems with your ECG, but I love that these devices are getting smarter and in more convenient packages.
Sample ECG Report
Here’s an ECG report I got after wearing the Wellue ECG Monitor.
The Cons about Using the Wellue ECG Device
First off, the chest strap is useless for me. And while I do see that they are trying to make it easy for you to get into monitoring your ECG, I wouldn’t use this unless you’re not going to be doing a lot of movement. So if you’re just doing an ECG for a shorter period of time and you know you’ll be relaxing, maybe that’s a good time to use it.
Secondly, if you do decide to use the electrode patches, know that when you purchase them, it comes with 10 patches. And once you open the packaging, it says that you want to use them within 30 days.
So if you’re going to be using it more long-term or at some later point in the future, you’ll have to purchase additional patches. Fortunately, they aren’t very expensive.
Besides those few really minor issues, the convenience you get using this as opposed to some of the other more cumbersome Holter monitors is pretty awesome.
Do I recommend it? Well, if you’re trying to get a detailed view of the electrical activity of your heart, this is a great tool. I’ll be using it at least once a month to get an idea of where I stand. Although knowing myself, it’ll probably be much more than that.
