Wellue AI Heart Health Monitor, 24 Hours Holter with Free AI Analysis & PC Report, Chargeable Home Heart Recorder

Update: I recently had a 24 Holter exam done through my cardiologist's office. I wore my Wellue monitor for much of that time and was able to compare the summary Wellue report for my session with the report received by my cardiologist. The Wellue report contained all of the same types of information as in the cardiologist's Holter report and the results from the Wellue monitor were closer to those of the Holter than I thought they would be. Since I wore the two monitors for different lengths of time, instead of comparing the total number of different types of arrhythmias, I looked at them as fractions of the number of beats each monitor recorded. As I suspected (see my original review below) the Wellue monitor missed many PACs and PVCs, however, it caught 85% of them which is a level of accuracy sufficient to detect any significant issues should they arise. That is very impressive for a product that is so accessible and easy to use.Original Review: Great idea, but the analysis algorithms need improvement. It is really useful to have ecg readings extending over longer periods than is possible with the Kardia devices and Apple Watch. Much more revealing of underlying issues. Unfortunately the "ai" analysis misses many PVCs and PACs and I find myself scanning the full ecg to get a more accurate understanding of what it is revealing. Despite this, I am finding it very worthwhile and have stopped using my other cardiac monitoring devices. As an added bonus, the sensor can connect via bluetooth to give heart rate readings on exercise equipment and the sensor can also connect to the free ViHealth app to give real time ecg readings. Bottom line - highly recommended.

Review of Wellue Heart Health Monitor (ER1)Intended Use - Ambulatory EKG monitoring (up to 24 hours). Note the disclaimer that the device is not intended to replace the medical diagnosis of a professional physician.Hardware - The Wellue Heart Health Monitor (ER1) is a conveniently sized (1” x 4”, 18 grams) CE-marked device that is designed for ambulatory EKG monitoring. The device functions as a chest EKG monitor, and is attached to the chest in either of two ways: (1) with a conductive tension chest strap, and (2) with adhesive electrodes. It is designed with a non-replaceable lithium battery that is claimed to last for ~300 charge/discharge cycles.Software - The device is used with the ECG browser that runs on a Windows computer. Installation of the ECG browser using the USB key that comes in the box was straightforward and easy. The user needs to register online to activate the ECG browser. The browser acts as an interface between the device itself, and a powerful AI-guided analysis software that runs in the cloud. The ECG browser seems well designed and operates without problems. There are no hidden fees or “per use” charges for the AI-driven EKG analysis. So the user only has to pay the up-front purchase price.Operation - In using the device over the past 4 months, I personally find the chest strap more convenient than the electrodes, but this may be a matter of personal preference. I have found that the strongest and most consistent recordings with the chest strap are obtained by smearing a small daub of electrode gel (easily and inexpensively purchased, e.g. through Amazon) on conductive part of the strap, to ensure good consistent electrical contact.I have found the chest strap to be unsuitable (contact is broken) when moving around too vigorously, such as when exercising. If one would like to use the monitor during vigorous activity, it may be necessary to use the adhesive electrodes instead, as you would with a Holter monitor.Reporting - Once the data collection is complete, the data is uploaded, through the ECG browser, to an offline server (in the cloud) where the AI-guided EKG analysis is performed. After several minutes, the results are available for download in the form of two PDF files: (1) a summary report, and (2) a detailed EKG trace which can run for hundeds of pages (depending on how long the recording is).For me, the summary report is extremely informative, and is where the true value of this device lies. The report is highly detailed, and divided into sections:Basic Information:Name, Gender, Age, recording start and finish dates and times, length or recording. (More than one person can use a single device, so there need to be separate accounts, so that reports do not get mixed up between users.)Report Overview:Total number of heartbeats, % atrial flutter and atrial fibrillation, maximum / minimum / average heart rates, maximum RR interval duration, number of long RR intervals, number of asystole, when the longest asystole occurred.Supraventricular Rhythm:Number of supraventricular heartbeats, number of PAC, number of PAC couplets, number of suprventricular bigeminy events, number of supraventricular trigeminy events, number of supraventricular tachycardia events, max duration of supraventricular tachycardia, when the longest supraventricular tachycardia occurred.Ventricular Rhythm:Total number of ventricular heartbeats, number of PVC, number of PVC couplets, number of ventricular bigeminy events, number of ventricular trigeminy events, number of ventricular tachycardia events, max duration of ventricular tachycardia, when the longest ventricular tachycardia occurred.HRV (heart rate variability):SDNN, RMSDD, SDANN, SDSD, PNN50, TINN, LF, HF, VLF, ASDNN. (These are quantitative parameters that describe heart rate variability.)ECG Report Conclusion:A top level summary of observationsHourly Statistics Table of ECG Data:This is a tabular presentation of the data, divided into hourly intervals, and showing the number of beats, the average /min /max heart rate, number of asystole events, number of ventricular beats, PVCs, PVC couplets, PVC runs, # PVC bigeminy, # PVC trigeminy, number of atrial beats, PACs, PAC couplets, PAC runs, # PAC bigeminy, # PAC trigeminy, duration of any bradycardia events.The hourly statistics table is particularly informative if one is measuring for long (multi hour) intervals, as it allows one to see differences in ECG patterns during sleep vs wakefulness.As part of this review, I provide an example ~1 minute portion of an EKG that I recorded with the chest strap. Points to note: The EKG signal is very strong and consistent. I could easily identify the PQRST features of the EKG. The trace has both an x-axis calibration bar (1 sec) and a y-axis calibration bar (1 mV). The actual time of recording is indicated in 1 minute intervals. It is very easy to identify two isolated PVCs (premature ventricular contractions), present in the bottom trace at 19.48:38.Points for possible improvement - (1) My version of the ECG browser only runs on a Windows system. It would be useful to have an Apple Mac version as well. (Perhaps Wellue has made a Mac version in the time since I purchased my device.) (2) It would be helpful if the User Guide listed all of the “over 104 heart issues in 16 categories” that, according to the promotional material, the AI software is able to detect. (3) It would also be helpful if more description was given, of the training / validation studies that were performed to ensure that the AI-driven software was operating correctly. It is stated that “the AI database contains 50 million accurately labeled data fragments from 300,000 users”. However no more detail is provided.My overall impression - I find the Wellue Heart Health Monitor (ER1) to be an extremely useful tool, as I need to be proactive about my heart health, and cannot rely on occasional, very limited and expensive visits to either a general practitioner or cardiologist within the United States healthcare system. As many other people have discovered, it is increasingly important to take into one’s own hands the sort of general wellness monitoring that this device can provide. An important point, worth emphasizing again, is that there are no hidden fees or “per use” charges for the AI-driven EKG analysis. So the user only has to pay the up-front purchase price. I have shown an example report to my general healthcare provider, and also to a cardiologist. They considered it to be beneficial for monitoring between visits.I believe the device is excellent in the capacity described above as a wellness monitoring tool. It provides a wealth of detailed EKG data that can be used for trending, and that can also be sent to one’s healthcare practitioners. The device has easily surpassed my expectations, and I recommend it highly, without reservation. Five stars.

The product must be registered to sign in to use. The registration would not accept ANY of 30-40 password combinations. I attempted to contact the company. I used Amazon messaging AND sent an email to the only email address in the user manual. SILENCE!I then contacted Amazon and they had me do another Amazon message. I final get a response from Wellvue that tells me to send an email to a service email addy (not included a) in the manual b) on the registration page in case there is a problem c) anywhere else one would reason to look for help.That response tells me that there are KNOWN problems with registration because although the password instructions say there is no special character or space restriction: "Password length must be 6-20 characters. Must contain letters and numbers. Special characters and spaces are not restricted."only these special characters are supported (~!@#$%^&*). THIS IS NOT TRUE! The system will not accept the first 4 characters as part of a password. A password with only letters and numbers finally had to be created. All of this is something that should be included in the manual and READILY available as a response to the Q&A on the page AND be immediately offered in response to any question about a problem registering.
