Choosing Asan Medical Centre for CRT - D gives patients access to experienced cardiac specialists, advanced electrophysiology technology, and comprehensive cardiovascular care. Established in 1989, the ISO hospital in Seoul, South Korea has 2700 beds and provides specialised cardiac services.

CRT-D may be considered for patients with certain types of heart failure who have reduced pumping function and an electrical conduction abnormality that causes the ventricles to contract asynchronously. The device delivers coordinated electrical stimulation to improve ventricular synchrony while providing defibrillation therapy when needed. Before implantation, doctors perform cardiac investigations to assess heart rhythm, ventricular function, and the risk of serious arrhythmias. Follow-up visits help monitor the device and the patient's response.
