The body's natural pacemaker, the sinoatrial (SA) node, is not working properly—this can cause the heart to beat too slowly
There are malfunctions in the atrioventricular (AV) node, which is the part of the heart’s electrical system that sends signals from the SA node to the ventricles—this leads to a slow heartbeat
Heart performance in people with severe symptoms of congestive heart failure and a weakened heart muscle, known as
cardiomyopathy, needs to be improved—his is called biventricular pacing, or cardiac resynchronization therapy
You will lie flat on a
table. Your heart rate, blood pressure, and breathing will be monitored. The doctor will make a small incision beneath your collarbone. The pacemaker will be inserted through this incision. The wires will be threaded through a vein under the collarbone to your heart. Lastly, the incision will be closed with stitches.
