This software seems to be based entirely off of Apple Watch ECG feature of putting your finger on the crown for 30 seconds. During that time you have to be still, which means you can’t use it during heavy exercise. I was also under the impression Apple Watch couldn’t detect PVCs. So just how useful the ECG feature is on Apple Watch is still a mystery to me. I do own Apple Watch 9, and every usage of ECG says “this ecg doesn’t show any signs of…”.
In contrast, hospital grade devices, like Holter, are worn over the heart for 48 hours as you live your life normally, exercise and all. The entire period of time is later analyzed.
In terms of some metrics a consumer grade chest strap, like Polar H10, is considered superior to wrist worn devices, such as staying connected while moving around, providing continuous readings, etc. Why doesn’t ECG+ have an option of directly collecting chest strap readings for a variable duration, like hours, even while exercising? In my opinion, this ECG+ isn’t built on the strongest foundation and I can’t see how it’s worth $120.
