Cardiac Resynchronization Therapy

Cardiac resynchronization therapy, also known as CRT or biventricular pacing, is a procedure for implanting a special type of pacemaker. A biventricular pacemaker helps most people who have this procedure get both of their heart ventricles contracting at the same time. This can help people with heart failure have a better quality of life.

How does CRT works?

Unlike other pacemaker that have one or two wires or leads, a CRT, or biventricular pacemaker, has three. One lead goes to each of your ventricles. The third goes to your right atrium, one of your heart’s upper chambers. (Your heart has two ventricles and two atria.)

These leads watch for abnormal heart rhythms and send an electrical signal to correct them and make your heart chambers work together.
