Answer:
A cardiac pacemaker is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chamber to contract and therefore pump blood by doing so this device replaces and/or regulates the function of the electrical conduction system of the heart. The primary purpose of the pacemaker is to maintain an adequate heart rate, either because the heart’s natural pacemaker is not fast enough or because there is a block in the heart’s electrical conduction system.
