Frequently when I am walking up and down hills my chest starts to hurt. After a couple of minutes the pain stops and i can keep going without further problems. The top # on my pacemaker is set at 150bpm. This never happens when I am working out at the gym with a trainer. Ekg shows that my rhythm changes for several seconds when my HR reaches around 150. Could the two be related? If so, why would my rhythm change.
Thanks, Jim Owings
