1 Answer

Answer :

(3) Initiation of heart beat Explanation: A pacemaker is a medical device that uses electrical impulses, delivered by electrodes contacting the heart muscles, to initiate and regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's native pacemaker is not fast enough, or there is a block in the heart's electrical conduction system.
