Cardiac Resynchronization Therapy Altered the Severity and Pattern of Sleep Disordered Breathing in Case of Heart Failure with Systolic Dysfunction

69-year-old men with heart failure (HF) due to dilated cardiomyopathy (DCM) was referred for cardiac resynchronization therapy (CRT). He has frequent episodes of hospitalizations for acute decompensated heart failure (ADHF), requiring catecholamine-administration. He has functional class III-IV symptoms, AF with complete left bundle branch block (CLBBB) in electrocardiogram, and left ventricular ejection fraction (LVEF) of 20% in echocardiography. Considering previous history of ventricular tachycardia (VT), CRT with defibrillator (CRT-D) was implanted.
