Breakdown at 130
I recently had a Pacemaker implanted and was told that I would be able to get back to my normal routine of running and biking after a 6 or 8 week break. When I came back and started running, all went well at first (1st month or so). After that I started having trouble running at all. When I got my heart rate to about 100, I'd start getting missed beats (about 1 in 3 was missing). So, obviously I couldn't keep running, so I'd start walking until my heart 'steadied out'. Then I'd repeat and have it happen all over again. The effect was, I couldn't run. Then I went back to my doctor for a PM check and I told them about it and they said that my PM was set for 120 bpm maximum and that the PM must be interfering with my heart at the higher rates. So.....they changed the upper limit to 150 and I tried to run again. The same thing happened as before except now the threshhold of skipped beats is at about 130 BPM now. Has anyone had ANY kind of situation similar to this? Thanks.
