Mine has been very high lately. Up to 144 when standing or only walking a few steps and about 110 resting. This also seems to exacerbate the headaches. Mine got higher all of a sudden in the middle of recovery. I was testing to see if I had an egg allergy. When I tried having 8 eggs in 2 days after no eggs for a month, this very high heart rate started. I hope it goes back down after the eggs are out of my system.
