Sudden pulse drop while exercising
I posted this before, thought it was resolved but is returning. The PM was put in 5 years ago to resolve a total blockage of the signal between chambers when at rest.. While exercising, particularly on extended vigorous efforts such as on an elliptical machine, my pulse builds to the 140's (I'm 72 and have never had a high pulse rate). It then may drop suddenly to 100-120 and bounce back after 5-10 seconds. It used to be more dramatic when it would drop to 85 and stay there until I stopped the effort. I traced the trigger to caffiene and the probelm went away for about 18 months after I eliminated caffiene. Recently, it has come back as described above. So far it's an irritant but I'm concerned it will again progress to it's previous level. My PM limits are 60 and 170. Any thoughts?
