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?

That sounds like rate response! The pacer senses movement, assumes we are exerting, and raises our rate for us. It can take a few tries to fine tune it so it doesn't go up inappropriately. It's harmless, just feels weird if you aren't expecting it. If it's bothering you, or if your rate isn't going up enough when you exercise, give them a call. Otherwise, nothing to worry about.

Thanks! It doesn't bother me...yet! But why only with the left arm? Wouldn't rate response be to overall exercise?

In theory, it would catch any exercise. In reality, it's on the left side and the pacer itself is what senses the motion. It sounds like you might feel better with it turned down a bit. It comes with different sensitivity settings.

I talked with my Cardio Doc's device specialist. Sh said she's never heard of anything like this in 25 years. An appointment has been set up with me and a visiting device tech specialist from the company. 

Heart rate

The plot thickens. When I wave my left arm sideways for 15+ times my heart rate soars to 130+ and I feel faint. 5 minutes later I still feel like I've run a mile. I know, I know: "Stop doing that." Luckily it's not an action I would normally have to do, but it implies that my Pacemaker is responding too much to a particular mild exertion. Stay tunes.

Since I got my pacemaker, I don't pass out anymore! That's a blessing in itself.
