People who have heart issues or cardiac arrhythmias (abnormal heart rate) need help to regulate their heartbeat and sometimes need a pacemaker. The device is made up of a small generator and leads or wires; a surgeon implants the pacemaker under the skin to manage these irregular heartbeats. It uses low-energy electrical impulses to help the heart beat normally. Different types of pacemakers offer options to treat heart issues of varying type and severity.


1. What Does A Pacemaker Look Like?

A pacemaker is generally the size of a fifty-cent piece and three times as thick, and is composed of biocompatible materials that are safe when in contact with living tissues. It has an overall casing of titanium and leads encased in polyurethane. The lead is attached to the battery or generator component and then, when implanted, placed inside the lower right ventricle. If a patient requires two leads, the second goes inside the upper right chamber.
