An artificial pacemaker is commonly implanted to treat

Heart block is a condition in which the conduction of impulses from the atria to the ventricles is interrupted. Heart block is treated by the implantation of an artificial pacemaker. Artificial pacemaker was introduced by Chardack (and Greatbatch) in 1960. There are two types of artificial pacemakers: temporary and permanent. The lithium-ion battery is the most common type of battery used in pacemakers.
