University Hospital Quironsalud Madrid provides specialised CRT - D with a focus on patient safety, precise device implantation, and long-term cardiac care. Established in 2006, the ISO, JCI hospital is located in Madrid, Spain, and operates 575 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.
