[Abstract]:A patient with dilated cardiomyopathy (DCM) was treated with (CRT). By double chamber pacemaker and single left ventricular pacing with frequency adaptive atrioventricular delay (RAAV) function. After 6 months follow-up, QRS wave duration narrowed from 170ms before operation to 118ms, left ventricular end-diastolic diameter (LVDd) decreased from 78mm to 49mm, left ventricular ejection fraction (LVEF) increased from 32% before operation to 48 mm postoperatively, cardiothoracic ratio increased from pre-operation to post-operation. The (NYHA) cardiac function grade of the New York College of Cardiology was reduced from preoperative grade 鈪，
