pacemaker

A pacemaker (or "artificial pacemaker") is a medical device designed to regulate the beating of the heart. The purpose of an artificial pacemaker is to stimulate the heart when either the heart's native pacemaker is not fast enough or if there are blocks in the heart's electrical conduction system preventing the propagation of electrical impulses from the native pacemaker to the lower chambers of the heart, known as the ventricles. People with Pacemakers are naturally weak and would otherwise die, but with a pacemaker are able to live through the miracles of modern science, thus making them part robot inside.
