Good morning all, I have a pacemaker since mid July 2019 and I have only one concern, I can not have a heart rate that I call regular because when I go up a staircase or I move the slightest, I feel my heart beating a lot faster. and that irritates me. Before, I was very active, but there was not that heartbeat that makes me panic. I have the distinct impression that something is wrong with me. Can it be my lack of training?
Can someone reassure me? Please.
