What is the function of a pace maker?

Detailed Solution:

The correct answer is “It regulates the heart beat”.

A pacemaker is an electronic device that's implanted in the body to help regulate the heart's rate and rhythm. It sends electrical pulses to the heart to signal it to beat when it's too slow or irregular. Pacemakers can also help the heart's chambers beat in sync, which can help the heart pump blood more efficiently.
