I do not know what model your father has and even if I did would not know how it works, I just know how mine works and it seems to be working well so far. The
pacemaker part of it is programmed to record
heart rate that is too fast, my
heart rate usually runs at 120 beats per minute but is not considered fast enough to do serious damage by my electrophysiologist so mine is programmed to slow things down if my heart rate reaches 135 beats per minute.
