Unnecessarily rapid pulse
I am 81 years old and in pretty good shape. I had a PM installed on Nov 13, 2020 because of afib/Bradycardia. That brought on a very high PR condition (120) with chest pain when I tried to walk 100 yds. Then that resulted in 3 stints for 99% blocked arteries. Now I can walk 20 minutes slowly with a PR of 100. Before any of this, I could walk a mile with a 78 PR. I climbed 3 flights of stairs today which resulted in a 159/88 BP and a 110 pulse. My Cardio Dr. says that the PM is not running my PR that high and it’s my regular heart rate doing it. Could it be that I didn’t need the PM in the first place and all my “slow to catch up HR” was because I had blocked arteries?
