I'm one who uses the AliveCor 2 pad devices on the iPod. My only problem with it has been that due to shaky hands I have to rest it on a solid surface and then do the test. Shows very interesting waves. I look for PVCs, but occasionally I pick up an A-Fib. The PVCs will show up as a quick and much smaller beat behind a regular beat followed by a space before another regular beat begins a new series of regular beats.
I read up and found that the little beat sends a smaller amount blood and the heart then has to wait until the regular amount is collected again.
AliveCor has stated they have no interest in PVCs. However, in my own experience, PVCs are far worse.
Glad you joined us here. I also use a PulseOxy fingertip devise to check my O2 sats. Those are also very important. This virus has caused numerous to deal with O2 sats, so knowing those as well is also an important devise to obtain.
