Trained athletes can have heart beat of 40, but I ain't one of those, and nor are you. I was getting down to the high 40s with long rest. The cardiologists were concerned, and cut my amiodarone dosage in half. Have only seen 48 twice since then. Surprisingly, the second time was during clinic testing on Wednesday, but the rest of the day it was in the 60s.

I hope you can avoid the pacemaker.
