I am 10 weeks post chronotropic for atrial flutter. Prior to this I suffered asymptomatic bradycardi and ectopic. This progressed to flutter with resting pulse varying from 40 to 140. After chronotropic I now have permanent bradycardi and a low maximum heart rate of 117bpm. No ectopic. I am still asymptomatic and despite the low maximum heart I can run 5 miles 2 or 3 times per week with no abnormal discomfort. Some of this I have reported previously. However I have read recent that this low maximum heart rate is described as chronotropic incompetence which apparently does not have a favourable prognosis. Any members knowledge or experience would be appreciated.
