Apollo Multispecialty Hospitals offers advanced CRT-D (Cardiac Resynchronisation Therapy with Defibrillator) using modern cardiac electrophysiology techniques and internationally accepted treatment protocols. Established in 2003, the JCI, ISO hospital is located in Kolkata, India and has 700 beds, providing comprehensive care for local and international patients.

CRT-D is a device-based treatment for selected patients with heart failure and abnormal electrical conduction that causes the ventricles to beat out of sync. The device helps coordinate the heart's ventricular contractions and can also deliver an electrical shock when a life-threatening abnormal heart rhythm occurs. Before implantation, doctors evaluate heart rhythm, ventricular function, and overall cardiac health. Regular follow-up is required to monitor device function and adjust treatment when necessary.
