心脏再同步化治疗(CRT)或心脏再同步化并植入心脏复律除颤器(CRTD)是近年来发展十分迅速的人工心脏起搏技术。CRT在传统单腔、双腔起搏器的基础上改良为左、右心室及右心房三腔起搏,使房室间、室间及室内同步激动,纠正了心脏的电-机械失同步,从而改善了心脏的电生理功能。对于存在室性心律失常危险因素的患者加植埋藏式心脏复律除颤器(ICD),即可预防心源性猝死的发生,显著降低病死率。因此,CRT/CRTD在心力衰竭的治疗中拥有广阔的前景。
Cardiac resynchronization therapy (CRT) or cardiac resynchronization and implantation of a cardioverter-defibrillator (CRTD) is a rapidly developing artificial heart pacing technique in recent years. CRT in the traditional single-chamber, double-chamber pacemaker based on improved left, right ventricle and right atrial pacing in three rooms, so that room, room and indoor synchronous excitement, corrected heart electromechanical loss of synchronization, Thus improving the electrophysiological function of the heart. For patients with risk factors for ventricular arrhythmia plus implantable cardioverter-defibrillator (ICD), can prevent the occurrence of sudden cardiac death, significantly reduce the mortality. Therefore, CRT / CRTD in the treatment of heart failure has a bright future.
