Cardiac Resynchronization Therapy Defibrillator (CRT-D) Surgery in Bangladesh
For patients with heart failure, a CRT-D is an implantable cardiac resynchronization therapy (CRT) defibrillator. The unit tracks the heart’s rhythm, senses disturbances, and uses electrical impulses to correct them. A CRT-D, like an implantable defibrillator (ICD), is designed to use relatively mild and painless induction therapy or electrical shocks to avoid life-threatening ventricular tachycardia and fibrillation. CRT-Ds vary from ICDs in that they aid in the coordination of your heart’s lower chambers, the ventricles. CRT-Ds, unlike ICDs, have three leads – wires that carry energy to the heart – instead of one or two.
