What does a pacemaker do?
टीपा लिहा
उत्तर
Pacemaker is a medical device which uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart.
The primary purpose of a 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 conducting system.
