ECG Monitor, Professional Holter Recorder with AI-ECG Analysis Report, 24-hours ECG Holter Record, Support PC Software, ECG Waveform PDF Printing, Portable Heart Health Tracker for Home Use

(I have given my review 5 stars but if there had been an opportunity I would have given it only 3 stars for the user friendliness of the PC software.)Installation of the Windows software from the supplied USB stick is straightforward (and, I assume, is similar for Mac).Before the ER1 Monitor is first used it is connected to your computer to synchronise time so that recordings will show the correct times. In my haste to get started I neglected to do this so my first recording showed the incorrect time and date.Using the device is also very straightforward. I didn't use the supplied electrodes as attaching the device to the body strap was simple and caused no discomfort while it was being worn, not even in bed.After wearing the monitor it is connected to your computer to allow the ECG data to be downloaded and then exported for AI analysis. This was the most difficult part of the operation as the software lacks user friendliness and the documentation is not very helpful. It would be friendlier, for example, if the button to close information windows was labelled 'close' rather than 'confirm'.The first few times I tried the software I found no way to quit and had to use Task Manager to end the application.The steps are as follows:Connect the device to your computer and start the AI-ECG Analysis System.Choose Import data (or Download data in an earlier version of the software).In the pop-up box set up a new user (or choose an existing user), then press ConfirmThe data is imported from the device and you can then View ECG or Analyze.View ECG shows the data in graphical form covering many pages.Analyze asks for permission to upload the data to the AI-ECG Platform, and this is the part of the process which is very poor.Once it has been submitted you are told it takes about 30 minutes to analyse each piece of data. As you aren't sure what is meant by 'each piece of data' you might worry that the analysis could take a few years.Also, you are not told the nature of the notification so you might waste a lot of time checking your email looking for a message that will never arrive.If you look carefully you may see that a very small number with an orange background has appeared next to the Notifications tab at the top of the page. This is the notification you have been expecting but you can do nothing about it as the application appears to be frozen. This where I resorted to using Task Manager to escape.In fact, what you need to do is close the information box that tells you the data has been submitted. The close icon is small and easy to miss. Once you have closed it you can click on the Notifications tab and a dropdown list gives you just the first few words of a message to say that an analysis of your data has been completed. You can then View Report.All this sounds quite a mission but it's not quite as bad as I've made it sound and, once you've used it a few times, the quirkiness of the software ceases to be an issue.Seeing the report makes it all worthwhile.The analysis report provides a wealth of information covering the duration of the ECG recording. I had always assumed that my heart was functioning normally but all the recordings I have made with the ER1 are consistent in showing that I have a number of issues which need to be brought to the attention of my doctor.My wife, on the other hand, who suspected she might have heart problems, was delighted that her analysis showed nothing to be concerned about.I just wish that this device had been available to me earlier in my life.One final observation: the manual states that the device will start and stop automatically when you 'put it on/off your body' but I found that the indicator light continues to blink all the time. Wellue say that this can't be turned off and the standby mode of the device is very energy efficient.Postscript added 15 October 2023As the ECG Monitor indicated that I may have heart issues, my doctor advised me to visit a cardiologist. After he'd examined the results of one of my 24-hour ER1 recordings he said that the device may well have saved my life. He was happy to accept the AI report which pointed to atrial fibrillation which could have caused a stroke at any time. If I had not used the ER1 my condition would have gone undiagnosed as I was not experiencing any symptoms.

I have amended this review from a previous poor rating due to an issue being resolved, whilst it is resolved the risk of reoccurrence and lack of official explanation has caused me to knock off a star.So, the product is actually an incredible bit of kit, its easy to use, comfortable to the point you forget you are wearing it, records with no issues for a full 24 hours. Slightly annoyed the first one came with a broken charging dock and not sure spares are easily available long term, but a replacement fixed that so no complaints there.The AI part of the system is what makes this product what it is, 24 hours of ECG without this analysis is not much use. The way this works is that the ECG is submitted to a server, 30 mins or so later data points and a report are generated and sent back to the software in an easy to digest format.My issue related to a period of around a week where the analysis was not sent back, all of a sudden it downloaded though. Reading another review online at amazon.com and a few news reports it seems this could have been linked to server or power issues in China. I wouldn't have minded at all, but no support requests answered, nothing on their site or notifications sent to users etc, so for a week I had a useless product. I would not have minded at all if this was communicated so I (and others) knew what to expect, if it had been the review would have been 5 stars... BUT... I don't know if this is a frequent or one off issue, why it was caused, will it happen again etc.Summary: great product but communication from the manufacturer less so. I just hope the issues were a one off and remain hopeful the product will do what it is was sold to from now on.

For my purposes, this 24 hour ECG monitor was really good. I had been experiencing some new heart symptoms and I bought this monitor to find out what was going on. I recorded my ECG for a period of about 20 hours, obtained an AI-analysis and sent it to my cardiologist. Importantly, my cardiologist commented:"The AI interpretation of your ECG recordings is very good and I cannot argue with the interpretation."As a non-specialist, I did not know what the AI-generated report meant and there is no analysis aimed for the lay person. But, if an ECG reveals potential heart defects, you anyway need expert analysis and the lack of an explanation for the lay person is no loss. What was important was that there was a delay of only a few days between my ordering the ecg monitor and sending the report to my cardiologies, by-passing a huge amount of delay that I would otherwise have suffered.I found no real problem with set up, except that my virus software (Bitdefender) blocked loading of the software from the memory stick on which it is provided, requiring me to work out how to create an exception for the software so that Bitdefender would allow it to be put on my laptop.In order to maximise the ECG quality, I attached the monitor to my chest with two of the supplied 3M electrodes. The device was comfortable to wear and did not interfere at all with what I was doing. When I finished monitoring, I removed the monitor from the electrodes and attached it to the connector device to allow the data to be downloaded to my PC and processed by the software. The AI analysis is carried out remotely: click a button and off go the data for analysis. The report came back quickly, perhaps within 10 minutes, as a pdf file.Of course, the monitor could have additional functions. What might be especially useful would be a button to press on the monitor when the wearer experiences an event, so that the corresponding ECG section can be identified. For some purposes, it would be useful to have a real-time display on one's phone and a heart rate monitor. However, for its job of acting as a Holter monitor, this is a 5-star device that will save you some of the frustrating delays built into the NHS.
