Crossing my PM upper limit of 145

Thanks, jc76. I have talked to Boston Scientific at some length and they never used the term exercise mode. I’m trying to get my terms right. I will call them back and ask them if the exercise mode is what they call the motion sensor or the breathing sensor. I suspect it is the latter. Both of these are turned on in my pacemaker. The ep and I have been making changes in the settings.

So now I’m thinking maybe I should shut one of them off and see if I feel better. I also have my pacing set to 70 and 150.

These devices are super complicated and not easy to figure out. Unfortunately I had this pm inserted four years ago and only recently learned that the settings could be changed for better results.

I have had one since 2006. I am still learning what they record, do and can do.

Like you I did not know my device even had an exercise mode until 2023. When the pace tech was setting me up to get a MRI. She mentioned exercise mode could help with my exercising as saw I was avid exerciser. I did not think anything about it until 2 days later got God awful fast and powerful pacing of my heart. Then happened again days later and got shocked.

The only thing different was the exercise mode turned on. I asked them to turn off. They wanted to try a lower reaction to movement saying mine set to high response. I said no I don't want it on as I had no problem exercising prior to it being turned on.

I had my present one (on 3rd) in 2018. I have read and was told by Mayo Pace Clinic that newer ones have a breathing monitor (like yours) which more reflects exercise where you are breathing faster and deeper versus just moving. My exercise mode pushed my heart rate up dramatically from just standing up as was recorded by my tech doing office check.

Not a medical person but my heart is paced at 70 bpm and does not go below that. It also has the same 150 you have. I think the heart being continously paced at 70 bpm and then exercise mode kick in sensing motion, and then my heart reacting normally to increase movement was confusing my device and reason I got shocked.

My settings are almost always changed each time do an office visit. They are always changing this electrical pulse strength, or monitoring, or changins sensing. I have been told I have noise on my wires in atrial area and my device thinks it is AFIB. But it is not it is the devive picking up noise (electrical) from the wires (my wires are very old all the way back to 2006). They tell me the device is being too sensitive and they adjust what it sensitivity setting are.
