Cardiac Resynchronization Therapy, is a treatment approach used in cardiology to improve the heart’s pumping efficiency in patients with heart failure and abnormal electrical conduction.
During a CRT procedure, a specialized device, known as a biventricular pacemaker or cardiac resynchronization therapy device, is implanted under the skin of the chest. The purpose of CRT is to coordinate the contractions of the heart’s chambers and restore synchronous pumping. The device delivers small electrical impulses to the heart, stimulating the ventricles to contract simultaneously, thereby improving the heart’s efficiency and blood flow.
CRT is typically recommended for patients with heart failure who have a reduced ejection fraction (a measure of the heart’s pumping capability) and have shown evidence of electrical dyssynchrony.
