HR spikes

[Stentrunner]

Since my PCI and stents followed by a lockdown PAF diagnosis, I have occasional asymptomatic heart rate spikes while exercising (see screen grab).

I have no idea whether these are real or simply Apple Watch aberrations. I always stop running and walk when I notice them. They are typically around 180bpm - well over my theoretical HRMax (I’m 72).

Anyone else had this?

Any thoughts welcome!

I think they are the Apple Watch having an occasional blip. I've read that it can double the actual rate on occasion momentarily. Mine certainly does this now and again and I can't believe it's possible for the watch to pick up such a sudden increase given the way it works.

~I have a Deluxe Fit-Bit - I have these spikes in heart rate with just moderate movement, or in the night asleep - my Cardiologist cannot explain (for some reason) but I am not really happy about these.

These have been occurring for some years as often picked them up on the treadmill @ gym.

I am almost 9 months post cryo-ablation but wonder if the steroids I take for a/i issues (8 years) are at fault here - not sure but only an assumption on my behalf.

I just wish they spikes would settle down as it's a daily occurrence and I am no closer to knowing why?! -

I am most reluctant to return to my gym classes so do moderate gentle walking at this stage - fitness is important to me.

Sorry not of any other help...

This might be off the wall, but.......I had been getting aberrant readings on my FitBit watch at night. Apparently I move around a bit at night, and the watch was misinterpreting this. When exercising (or for me, when sleeping), try wearing your watch tighter around the wrist. I found that tightening my watch at night (3 holes on the band rather than 2), the mysterious readings went away.

I have had this happen quite a few times. One time it was while my watch was sitting next to the sink while I showered (after I had already gotten it wet by accident). I picked it up and it said last heart rate recorded was 193 or something.

I think sometimes the sensor glitches like that. It's likely the movement during exercise + sweat etc confusing the sensor for a moment.

Thanks for your thoughts. I’m going to try some cross-checking. I’ve looked at the data from the watch - there’s a reading every second, and the spikes last between 10 and 30 seconds, and only occur when my pulse already high (135+). If I can catch one on my next run, I’ll try to take a radial or neck pulse with my finger. Failing that I have a finger-clip which reads pulse too.
