Heart rate spikes during sleep

[momo43]

Using an Inspire 2 tracker.  Consistently, EVERY night, I get a spike in my heart rate that falls mostly in the fat burn range but sometime goes into the next level.  The duration is variable, sometimes only one reading, sometimes spanning as much as 15 min.  It always occurs when the tracker indicates I am in light sleep but a few times during deep sleep (when the duration is longer).  Most curious, it always happens between 1 and 1:45 am,  I cannot correlate this with anything.  Any thoughts?

My PCP sent me to a cardiologist for testing. He ordered an Echocardiogram, 48 hour holter monitor and a stress test. He asked me if I had sleep apnea. I replied “not that I know of”.  I haven’t gotten the results of the testing back yet. BTW, after I updated the Fitbit software a few months ago I can’t find the heart rate charts like in the past. .  Not happy about that.

I have the same scenario in 2023 it was caused by something called atrial flutter my heart rate spikes to 140 or higher during the night and all day pretty much they put a monitor on  to track my heart rate. I end up having a heart ablation procedure to  to fix the problem which was electrical in my heart so it's nothing to mess around with

I would make an appointment with a cardiologist or electrophysiologist and get it checked out could be electrical problem in your heart
