The heart.
The part of the brain that regulates the pacemaker is the hypothalamus, specifically the suprachiasmatic nucleus (SCN). The SCN serves as the body's primary circadian clock, controlling rhythms such as sleep-wake cycles and influencing the timing of various physiological processes. It receives input from light cues, which help synchronize the body's internal clock with the external environment.
Pretty much any part of the human body that is either assisted or replaced by a mechanical equivalent. Like a prosthetic leg or hand, or even a pacemaker.
A pacemaker delivers an electric stimulus to the heart.
the answer is in the question. if the pacemaker is replaced the leads are used for it.
Pacemaker Defibrillator
To protect the parts of the pacemaker from body fluids as plastics are very unreactive and will not be affected.
An Artificial Pacemaker basically regulates the rate of the heart beat depending on the needs of the body.
The pacemaker will regulate the heartbeat, and a regulated heartbeat will regulate the speed blood is moved throughout the body. Improved blood flow, especially in the legs, will improve general health across the board.
the ear
The heart itself tells the heart to beat. It contains a small cluster of nerves that act as a biological "pacemaker".
