Biological pacemaker
Generally speaking, a biological pacemaker is one or more types of cellular components that, when "implanted or injected into certain regions of the heart," produce specific electrical stimuli that mimic that of the body's natural pacemaker cells. It's indicated for issues such as heart block, slow heart rate, and asynchronous heart ventricle contractions.
