how does a pacemaker know how fast it has to zap you?
People say it is programmed into a certain rythm, but what about when you exercise? isn't your heartbeat supposed to go faster then?

That does cause some trouble which is why they advise ppl with pacemakers and artificial hearts not to partake in strenuous activity.

Pacemakers have been used since the 1950s and come in various models. Older styles were designed to deliver beats at a predetermined rate. Other models use sensors that monitor the heart, only generating a pace or beat when the heart’s own beat becomes too slow or irregular. Dual-chamber pacemakers monitor both upper and lower chambers, ensuring they remain synchronized in a natural rhythm. The most advanced pacemakers are rate-responsive. These pacemakers monitor the body’s needs so that the heartbeat quickens on demand –- say for strenuous exercise –- and automatically slows when the body is at rest and demands are low.

I get it... :lol:
