A Pacemaker is a medical device that uses electrical impulses, delivered by electrodes contacting 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 native pacemaker is not fast enough, or there is a block in the heart's electrical conduction system. In this paper a review on the existing implantable pacemakers has been done along with the outline about the various other pacemakers in use. This provides a comparison between the products as well and thus gives a review of a suitable implantable pacemaker for the Indian market.
