What is this?
How is it possible during sleep for my heart rate or stress to jump that much? I do not sleep well per se, I do not wake up feeling rested. This is consistent so far. What could cause this?
These peaks are happening every night.

My Fitbit recorded my hear going from 76 to 190 while sleeping. I don’t remember waking up, nor my partner noticed anything weird. Can it be a glitch? It went up from 76 to 190 between 2.30am and 5am, with some gaps in between, shall I talk to a doctor?

This is a lead 1 of a phenomenon Ive documented few times reliably. Everytime I get an adrenaline surge when Im startled for example or nervous I get palpitations and this ecg change where a small negative deflection appears on the end of the st segement. It literally appears consistently as soon as I feel the adrenaline surge and then disappears as it wears off.
Could it be a t wave inversion? Maybe U waves? Its very pronounced on the watch and its not an artifact because it appears and disappears consistently. You can see it happening at the beginning there and then slowly disappear. Im not asking for a diagnosis just opinions on what that looks like. On a v2 it also looks like a tiny negative wave between a t wave and an u wave. This is a new phenomenon as well that started happening last few months.
Maybe just a normal response to sudden adrenaline release producing transient t wave flattening/inversion/u wave
I'm a pilot and pretty worried about my ECG. Attaching leads II, III and aVF. As I understand it, I have early repolarization in the inferior leads with a prominent J wave and horizontal ST segment, which is considered the highest-risk variant. Am I reading this correctly or not?

I have been feeling some very weird and sometimes fluttering heart beats recently. I was diagnosed with WPW and had an ablation about 1.5 years ago which seemed to correct everything. It feels like it’s back. What does it look like by the apple watch ECG? Thanks!
So I have lost 40 pounds over the last 7 months and my PVCs are 10x worse than ever. Lately they have been daily all day. Used to not be this way. I had a 30 day monitor back in January cleared fine no major events less than 1% load. Calcium score 0 on my scan. Echocardiogram years ago structurally fine. These are what my ECGs looks like constantly now.
