慢性心力衰竭是心脏病治疗上的难题,虽然随着血管紧张素转化酶抑制剂、β受体阻滞剂等药物的广泛应用,心力衰竭的预后有所改善,但仍保持较高的病死率。近年来心脏再同步治疗(CRT)在心力衰竭的治疗中取得了可喜的苗头,为心力衰竭治疗开辟了新的途径。CRT的基本原理是纠正心脏电机械,特别是左心室电机械的不同步性,使心脏收缩再同步化,从而改善心功能。本文就左心室同步收缩的病理 Chronic heart failure is a difficult problem in the treatment of heart disease. Although the prognosis of heart failure has been improved with the widespread use of drugs such as angiotensin converting enzyme inhibitors and β-blockers, it still maintains a high mortality rate . In recent years, cardiac resynchronization therapy (CRT) has achieved encouraging signs in the treatment of heart failure and opened a new avenue for the treatment of heart failure. The basic principle of CRT is to correct cardiac electrical machinery, especially the left ventricular electrical machinery asynchronous, systolic cardiac resynchronization, thereby improving cardiac function.
