Setting PM Upper Limit
At 7 weeks I'm doing great. (At 4 weeks I basically forgot I had a PM.) On my interrog. at 7 weeks, they reported that my dual pacer was pacing 75% upper and 0.1%(essentially 0) lower chamber. I'm on a BB (Inderal LA) for BP and an atrial arrythmia that I had before PM. The Inderal seems to have done the job. I still have PVC's, my Medtronic showed some 3000 in a 6 week period which is negligible. Luckily they are infrequent and when they do happen last only a few seconds. I made a good choice in the clinic/doc after several years of suffering through exercise induced problems
I'm trying to get back into running. My upper limit is 140, I'm not in the best shape, fast walking at 4 m.p.h for an hour is no problem but running at 8 mt pace can get me only to 1/8 mile (on my limited first attempt-see below) when my breathing got labored. I talked to the doc about raising my upper limit and he said that it is a misunderstanding that raising the rate will necessarily lead to better performance. At least there are diminshing returns when your rate is already at the recommended level for age (I'm 63). I didn't argue because I'm a long way from being in shape, not having run any distance over 1/4 mile in 4+ years due to my bradycardia and I didn't want to sound like a smart ass when everything the doc has done so far for me has been outstanding.
I'm interested in any comments from the knowledgeable here about this recommendation to keep my upper at 140. Right now I can't run because I pulled a thigh muscle the first day I tried and I'm prepared to live with the 140 max till I can show lack of progress after regular running.
