What is cardiac resynchronization therapy?

Texas Cardiac Arrhythmia Institute answered:Also called CRT or biventricular pacing, this procedure is a treatment for cardiac arrhythmias. It involves implanting an electronic device called a biventricular ICD or biventricular pacer that gets the heart’s left and right ventricles pumping together through small electrical impulses to the heart muscle.Also called CRT or biventricular pacing, this procedure is a treatment for cardiac arrhythmias.

Dr. Indrajit Choudhuri of Aurora Health Care answered:Cardiac resynchronization therapy (CRT) is a special way to pace the heart with two leads (one in the right ventricle and one in the left ventricle, the lower chambers). This kind of treatment is for patients with heart failure. It helps correctly time, or resynchronize, the heart’s contractions. CRT is also called biventricular pacing because both ventricles are paced at the same time. This can help a weakened heart pump more efficiently and lessen the symptoms of heart failure.Cardiac resynchronization therapy (CRT) is a special way to pace the heart with two leads (one in the right ventricle and one in the left ventricle, the lower chambers).

Brigham and Women's Hospital answered:A normal heart sends electrical signals to both lower chambers or "ventricles" of the heart to make them pump at the same time. Sometimes in heart failure patients, the two chambers do not pump together. A special pacemaker called Cardiac Resynchronization Therapy (CRT) is a small battery-powered device that is placed under the skin that helps make the two sides of the heart beat together. It has special wires called "leads" that send tiny electrical signals to the heart telling the heart muscle when to pump. CRT is a pacemaker that tells both ventricles to pump at the same time, so it has leads on the right and left side of the heart. CRT can reduce your heart failure symptoms and increase your ability to exercise and be more active.A normal heart sends electrical signals to both lower chambers or "ventricles" of the heart to make them pump at the same time.
