The pacemaker is a lightweight, electronic device that monitors the heart’s electrical activity and delivers electrical pulses, as the heart needs them. If the pacemaker senses that the heart is beating too slowly or pauses for too long, the pacemaker stimulates the heart with precisely timed electrical pulses. The pacemaker is implanted into the body, usually beneath the skin in the upper chest just below the collarbone.
