A pacemaker is a tiny device that is implanted in the abdomen or chest area to control abnormal heart rhythms. It utilizes electrical impulses to help the heart muscle maintain a proper rhythm and heart rate.
Pacemakers are mostly used to treat arrhythmia. The can also be used to treat hypertrophic cardiomyopathy, congestive heart failure and fainting spells. A typical pacemaker consists of a computerized generator, wires with sensors and a battery. Implanting a pacemaker requires a minor surgery that takes a few hours.
Complications due to pacemaker surgery are rare, and most people can resume their normal activities after a few days. However, precautions have to be taken in everyday life after a pacemaker has been implanted.
