Pacemaker

The primary function of a pacemaker is to treat or prevent slow heart rates. Slow heart rates may occur as a result of aging or diseases that affect the heart’s own electrical system or may be due to medications necessary to treat various heart conditions.

Introduced in the mid 1950s, these devices are typically implanted through a small incision under the skin in the region of the left or right collarbone.

A pacemaker consists of a generator (a battery with electronic circuits) and one or more electrode leads, threaded through a vein under the collarbone to the inside of the heart chambers. The pacemaker battery may last up to 7–10 years and individuals with a pacemaker should receive regular follow up to assure proper function of the device and the battery.

Modern pacemakers fit comfortably into typical everyday life, and do not interfere with any of the usual everyday appliances, such as microwaves.
