I am 76, had only one episode of tachycardia at 74 1/2, was medicated with two beta blockers, weaned off one with no problem, have weight-trained and run (now jog) for 35+ years, have large right atrium, take cozaar with no problems, and accepted the operation for a pacemaker set on at 60 (it was 40 to 50 bpm from years of running) with no problems. I have not had any further problems since the original flutter was easily stopped by cardioversion. Blood pressure is well controlled.
My problem is that my regular running workout 3 times a week was affected by the limit on exercise pulse immediately last year from the sotalol beta blocker, and I am considering weaning off the sotalol, in order to be able to restore my running effort beyond jogging. I am looking for medical advice beyond the weaning alternative, with the understanding that ablation has its own problems such as reoccurence of flutter, and almost all other medications have drawbacks in their side effects.
