It is simply an electronic metronome that produces low voltage and low current pulses at regular intervals on wires attached directly to the muscles of the heart. It is used when, for various reasons, the pulses driving the heart from the nervous system are too weak or too irregular for the heart to supply blood properly to the needs of the body.

A pacemaker is often used as a type of backup, it is going to kick in and initiate pacing the middle if the cost drops under a definite threshold, so until eventually the condition which makes the pacemaker needed prevents it, there is not any clarification why the middle fee won't be in a position to pass speedier in step with in spite of stimulus.

the pacemaker's are located near the heart, and it recieves the beats of motion, and when it notices that the heartbeat stops, it uses the memory of the past heartbeats to generate the best effective heartrate to give to the heart with an electrical pulse.
