Q: Where did you learn about Wellue and AI ECG Recorder?
I learned about Wellue from their partner Lepu Medical Technology and from the website getwellue.com. The first device that I bought was Wellue Smart Blood Pressure Monitor with ECG. I liked it so much that I ordered additionally 10 units for gifts for my friends and colleagues.
Q: What is your purpose of buying Wellue AI ECG Recorder?
Recently my father had an episode of what appeared to be a TIA and atrial fibrillation had to be ruled out as the cause. Of course, I have access to the ECG holters in my hospital. However, I chose to buy the Wellue AI ECG recorder because of the reasonable price, to skip the waiting list of patients and to evade hospital contacts during the most devastating coronavirus wave in my country. Besides, I was appealed by the small size, functionality, lack of cables, and ease of use of the device. The delivery was very fast (approximately one week). The recorder came in a small box with 10 ECG electrodes and a chest belt for the two different modes of attachment.
I performed several 24-hour recordings which served me to guide the medical therapy. At first the AI analysis didn’t work, but the support team was very cooperative and solved the problem quickly. As a cardiologist, I looked carefully through the whole recordings page by page. And when I compared them to the AI analysis reports, I was surprised how accurate they were. I have been working with different kinds of ECG holters in my practice. And I must admit that the AI analysis is at least as good as the professional analysis software of the other recorders.
The ECG report starts with an overview of the findings. You see the total number of heart beats, percentage of atrial fibrillation and flutter, maximum, minimum and average heart rate, and long RR intervals data. Next you can see details for supraventricular and ventricular ectopy including number of extrasystoles, couplets, tachycardias, bigeminy and trigeminy. Following are the heart rate variability indices which are quite thorough:
On the second page of the report you can read the conclusion of the AI analysis which is in the form of a list of the ECG findings:
The third page presents extremely valuable information – the distribution of the events. You can follow hour by hour the appearance of the different pathological findings. This feature is very helpful as it can give us some hints regarding the cause of the arrhythmias. Surprisingly it is not available in some of the other ECG recorders that I use in the hospital. In the present case almost all of the pathological events were during the night, which served as an indication to perform a sleep polysomnography study as well.
The remaining pages of the report show examples of the minimum and maximum heart rate, as well as of the pathological events with time of occurrence:
A detailed description of Wellue AI ECG usage
Wellue AI ECG recorder is extremely easy to operate with. The recording begins with the attachment of the device to the patient’s chest. A short vibration indicates a successful start. With the help of ViHealth application via a Bluetooth connection you can check the quality of the signal on your mobile phone. A thirty-minute recording on the mobile phone is also possible. The recorder is exceptionally compact and lightweight and the patient does not feel any discomfort at all. The recording stops automatically with the detachment of the device or if the maximum duration of 24 hours is reached. A fully charged battery can handle at least three 24-hour recordings. You can check the battery status with the ViHealth application or with the LED indicator on the device. The recording is visualized with the software ECG browser. You need to do a free registration and to have an internet connection to use it. The download of the data is fast and time saving. There is an option to export as pdf files single pages or the whole recording. A good feature is that you can switch the amplitude between 1.25, 2.5, 5, 10, 20 and 40 mm/mV. However, it is not possible to change the “paper” speed and it is fixed to 25 mm/s for single pages and 12.5 mm/s if you export the whole recording into a pdf-file. This certainly is not a problem as you can enlarge the pdf file for a detailed view.
To receive the AI analysis, you need to upload the recording to the AI platform. It usually takes less than 30 minutes to get the results. When it is ready, a list of the grouped events appears on the left side of the screen. Then you can scroll easily between the different events.
The main advantages of the device are its remarkably compact size, ease of operation and powerful AI analysis that will suit the needs of both general public and professionals. There are, of course, some small disadvantages like the lack of a backup channel in case of artifacts. The ECG browser could include some more functions like manual measurements of intervals.
Overall, I am fully satisfied with the Wellue AI ECG recorder and believe, that this is the future of the cardiology equipment.
