Cardiac Resynchronization Therapy
Medically reviewed by Drugs.com. Last updated on May 6, 2024.
Cardiac resynchronization therapy (CRT) is a procedure used to treat problems with how your heart beats. CRT is also called biventricular pacing. The 2 upper chambers of the heart are called atria. The 2 lower chambers are called ventricles. Your heartbeat is synchronized when all areas of your heart beat together properly. When the areas of your heart do not beat as they should, your heart cannot pump enough blood and oxygen to your body. You may have trouble breathing, tire easily, and have swelling in your legs and feet.
