Global Health City provides specialised CRT - D with a focus on patient safety, precise device implantation, and long-term cardiac care. Established in 1999, the NABH, NABL hospital is located in Chennai, India, and operates 200 beds, equipped with modern healthcare infrastructure.

CRT-D (Cardiac Resynchronisation Therapy with Defibrillator) is designed to provide both ventricular resynchronisation and protection against certain life-threatening abnormal heart rhythms. It is used in carefully selected patients with heart failure and specific electrical conduction abnormalities. The device uses leads to deliver electrical impulses that coordinate ventricular contractions and can deliver a shock when required to terminate certain dangerous rhythms. Comprehensive cardiac evaluation before implantation and ongoing device follow-up are important parts of treatment.
