A novel use of cardiac resynchronization therapy‐defibrillator device in hypertrophic cardiomyopathy

Dual‐chamber implantable cardioverter‐defibrillator is generally used in patients with atrioventricular block and hypertrophic cardiomyopathy with preserved left ventricular ejection fraction. In the current case, a cardiac resynchronization therapy‐defibrillator device was implanted in a patient with non‐obstructive hypertrophic cardiomyopathy with preserved ejection fraction and atrioventricular block to achieve both more physiological pacing and life‐threatening ventricular arrhythmia management.
