How ECG Monitor Help Prevent Heart diseases?

How ECG Monitor Help Prevent Heart diseases?

Heart disease is a leading cause of death worldwide and can also result in long-term disabilities and reduced quality of life for those affected. Many survivors require ongoing medical care and support to manage their condition, which can be expensive and time-consuming. However, efforts are being made to improve heart diseases prevention, care, and management around the world, including public education campaigns, expanded access to healthcare, and the development of new treatments and technologies.

Dr Frederico de Morais Ribeiro, a cardiologist from Brazil, has done a heart health monitor case study on Wellue ECG Monitor to research how it helps people detect irregular heart rhythms, or arrhythmias. By tracking their heart rhythm data over time, individuals may be able to spot patterns or changes that could indicate developing heart problems. Catching these changes early can mean being able to intervene and prevent the worsening of heart disease or other heart-related problems.

A 75-year-old patient with Arterial Hypertension, Dyslipidemia, Diabetes type 2 and recent episode of Transient Ischemic Accident, seeks the cardiologist for diagnostic investigation.

The patient had already undergone ECG, ECodopplercardiogram and Holter 24h all without abnormalities.

We then chose to do a longer Electrocardiographic Monitoring, using the Heart Health Monitor – ECG Recorder Wellue, which has a battery for 72h of monitoring. We used it attached to the thoracic with a strap, as it could be taken out for the bath, making the examination more comfortable.

At the end of 72 hours, we connect the device to the Computer and download all the data to the AI program – ECG Analiysis System, which through Artificial Intelligence quickly suggests a Report and makes available all the traces for conference and if this monitoring has been done by the patient, this data can be shared with your doctor very easily.

Below is the Report model generated by the AI-ECG Analysis System program.

It is a very complete and structured report, easy to understand and that can be shared very easily.

It presents data such as the time monitored, remembering that with each removal of the ECG recorder from the body, the device automatically turns off and reactivates automatically after being reattached to the body, maximum and minimum heart rate, main cardiac arrhythmias found, as well as the number of documented times and time they appeared. It generates a report with the diagnosis found and at the end has the ECG tracing showing the arrhythmias caught.

The program also has the visualization tool of the entire electrocardiographic tracing so that the doctor can check and confirm the findings exposed by the Artificial Intelligence.

Case Discussion:

In this case in question, the electrocardiographic monitoring of this patient by the ECG Recorder was very important, because an arrhythmia called Atrial Flutter was detected, in this case, in its paroxysmal form. It is known that this Arrhythmia has great thromboembolic potential, that is, to form clots inside the heart and these detach and go to the brain, causing Strokes.

With such diagnoses we make the risk stratification of this arrhythmia by means of Risk Scores (CHADSVASC2) and from these data we elaborate the treatment in order to reduce the risk of new Cerebral Vascular Accidents, a disease with a lot of morbidity and mortality.

ECG (electrocardiogram) monitoring is important for the prevention of stroke because many cases of stroke are caused by heart rhythm disturbances, such as Atrial fibrillation/Atrial Flutter.

Atrial fibrillation/Atrial Flutter is a condition in which the atria of the heart do not beat properly, which can lead to the formation of blood clots that can move to the brain and cause a stroke.

ECG monitoring can detect Atrial fibrillation/Atrial Flutter, enabling early treatment and prevention of stroke. In addition, continuous ECG monitoring can help identify other heart rhythm disorders that may also contribute to stroke risk.

It’s important to remember that stroke prevention involves many factors, including healthy lifestyle habits, controlling blood pressure, cholesterol, and blood sugar, as well as treating underlying medical conditions. ECG monitoring is just one of the tools available to help prevent stroke and should be used in conjunction with other preventive measures.

Do I Need Daily ECG Monitoring?

Do I Need Daily ECG Monitoring?

An Essential Way to Overall Health and Wellbeing

Maintaining good heart health is essential for leading a healthy and happy life. A healthy heart not only ensures optimal blood flow but also lowers the risk of developing heart disease and related complications. Monitoring the heart’s activity is crucial in identifying and preventing heart problems.

While regular check-ups with a doctor can help identify heart problems, daily monitoring of your heart’s electrical activity can provide valuable insights into your heart health.

Traditionally, heart monitoring required a visit to the doctor’s office or hospital, where you would undergo an electrocardiogram (ECG) test. However, advancements in technology have made it possible to monitor your heart’s electrical activity at home with devices like the Wellue 24-Hour ECG Recorder and Wellue 12-Lead Holter Monitor.

Do Ordinary People Need Daily Heart Monitoring?

The answer is yes. Heart problems can develop slowly over time, and daily monitoring can help detect changes in your heart’s activity that may be early warning signs of a problem. Additionally, if you have a history of heart problems or are at risk for heart disease, daily monitoring can help you and your doctor better manage your condition.

Resting ECG or Continuous ECG monitoring

An electrocardiogram (ECG or EKG) is a medical test that records the electrical activity of the heart. The test involves placing electrodes on the chest, arms, and legs to detect the electrical impulses produced by the heart. There are two ECG test types: resting and continuous ECG monitoring. We will discuss the advantages and disadvantages of resting ECG and the importance of daily heart monitoring.

Advantages and disadvantages of resting ECG:


  1. Non-invasive: The resting ECG test is a non-invasive procedure that does not involve any incisions or injections, making it a safe and painless test.
  2. Quick and easy: The resting ECG test takes only a few minutes to perform, and the results can be obtained immediately.
  3. Cost-effective: The resting ECG test is a relatively inexpensive test that can provide valuable information about the heart’s health.


  1. Limited information: The resting ECG test provides only a snapshot of the heart’s electrical activity at a particular moment. It cannot detect irregularities that may occur intermittently.
  2. False negatives: Resting ECG tests may fail to detect heart problems, even if they are present, leading to false negatives.
  3. Dependence on patient cooperation: The resting ECG test relies on the patient’s cooperation to obtain accurate results. Patients must remain still and relaxed during the test, which can be challenging for some individuals.

Importance of daily heart monitoring

Continuous ECG monitoring, also known as Holter monitoring, is a type of ECG test that involves wearing a portable device that records the heart’s electrical activity for 24 to 48 hours. Daily heart monitoring is crucial for individuals with known heart problems, those at high risk of heart disease, or those who experience symptoms such as chest pain, shortness of breath, or palpitations.

The benefits of daily heart monitoring include:

  1. Early detection of heart problems: Daily heart monitoring can detect irregularities in the heart’s electrical activity that may occur intermittently, which can be missed by resting ECG tests.
  2. Tailored treatment: Daily heart monitoring can help doctors determine the appropriate treatment for patients with heart problems by providing detailed information about the heart’s electrical activity.
  3. Increased patient awareness: Daily heart monitoring can help patients become more aware of their heart health, leading to lifestyle changes and better management of heart disease.

An Ideal Device for Continuous ECG Monitoring At Home

The Wellue 24-Hour ECG Recorder is an ideal device that allows for continuous ECG monitoring at home. This device is small and easy to use, and it attaches to the chest using adhesive pads. It allows users to record and track heart activity for up to 24 hours, providing individuals with a comprehensive analysis of their heart’s health.In addition, the AI-generated report and ECG waveform provide healthcare providers with a more comprehensive understanding of their heart health.

Some Basic Facts about EKG that You Have to Know

Some Basic Facts about EKG that You Have to Know

about ecg waveform

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;
  • Regular smokers.

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.

EKG Results

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:

  1. 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.

How to Do an ECG at Home?

How to Do an ECG at Home?

From: https://www.interactive-biology.com/

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.

For a more in-depth explanation, see our post that gives goes into more details about the ECG.

Holter Monitors

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. 

The Wellue 24 Hour ECG Recorder comes with disposable electrodes in addition to the chest strap for attaching the device to the body.

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.
