weird pacemaker issue
I have an oximeter which measures my heart. I noticed that my heart rate went up when I did a casual exercise like raising my arms slowly forward and sideways. I experinmented. It only happened when I did it with my left arm, the Pacemaker side, but not on my right. It would shoot up by 25-30 beats. I've had it in for 3 months. It would also do it the gym with certain upper body exercises, and once on the treadmill when I had my left arm up on the back of the machine.
Should I be worried?
