When I first got my new watch back in April (Epix Pro Gen 2), I played with ECG several times and it gave me some nice clean looking ECGs. I know I’ve done one since. Today, I was curious what it looked like. I cannot get an ECG that doesn’t look like total garbage. I’ve tried a few times throughout the day. I either get some noise or like four glitches at the start that die out and go to noise. No BPM show up either. I did update my watch software last week prior to going on a trip. What gives?
