When is a pacemaker needed?

Ravi K. Sureddi, MD
Clinical Cardiac Electrophysiology
A patient needs a pacemaker when he or she has problems from a slow heart rate. In this video, Ravi K. Sureddi, MD, a cardiac electrophysiologist at Riverside Community Hospital, describes various elements of a slow heart rate.

A person might need a pacemaker to be inserted for several reasons. These include:

  • Malfunctions in the heart's sinoatrial (SA) node, also called the body's natural pacemaker. When the SA node does not work properly, the heart can beat too slowly.
  • Malfunctions in the heart’s atrioventricular (AV) node, which sends electrical signals from the SA node to the ventricles. When the AV node malfunctions, this leads to a slow heartbeat.
  • Poor heart performance because of severe symptoms of congestive heart failure and a weakened heart muscle.
