I am 47yo male, and had one AFIB incident in 2017. I have a KARDIA ECG that I use to monitor AFIB which always shows normal rhythm. I had two DVT/PE's in past as well, and a history of "inappropriate sinus tachycardia". I take Bystolic(Beta Blocker) and Xarelto. I occasionally have days where my HR is elevated inappropriately. I will be sitting down, and it will be in the 90's-100's. My doctor has told me to take extra Beta Blocker when that happens.
Saturday I had been noticing elevated HR again. So at night, I monitored my HR. As you can see in the picture, during a portion of the night, my HR fluctuated wildly up and down. My average HR was around 85bpm, and peaked once at 112bpm. Usually my resting HR is in the 60's-70's. This appeared to happen during REM SLEEP. I did not sleep well and woke up several times feeling hot and had night sweats.
I'd like to know what is going on. I sent this to my Cardiologist and Electrophysiologist to examine. I'm hoping they will order another heart monitor for several weeks to catch this thing to figure out what is going on. When I woke up in middle of the night, I used my KARDIA ECG and it showed normal rhythm.
