@hearttoheart1 Hi and Welcome. I too for many years had a pacemaker defibulator and I thought I might add to what @river19 said. But when I had one I also had a bedside device that would monitor activity that was programmed to alert the doctor's office usually thru the manufacturer of the device mine was Boston scientific and if I had a concern I could download my device with a button on the bedside and call the office and they could get it checked to see if anything was a concern. It doesn't require going to the office and may give you some comfort as to if there are any issues. I do know how what I use to call phantom feelings something was wrong and come to find out it was only anxiety. I hope that helps please let me know if I can answer any other questions.
Have a Blessed Day
Dana
