概述

背景心脏再同步化治疗(CRT)是一种心脏起搏方法,用于左室收缩功能障碍合并心室激活不同步的患者,通过刺激左、右心室(双室起搏)或单独刺激左心室,使左、右心室的电活动同步或近乎同步。治疗原理CRT治疗时会起搏左心室,通常同时或近乎同时起搏右心室,让心室活动恢复同步化,从而改善存在左室收缩功能障碍和电不同步心电图证据患者的左室收缩功能和临床结局。指征窦性心律患者应根据左室射血分数(LVEF)、QRS波时限及形态、纽约心脏协会(NYHA)心功能分级以及是否需要心室起搏决定是否需要植入CRT。下列一般指

Cardiac resynchronization therapy (CRT) is a modality of cardiac pacing used in patients with left ventricular (LV) systolic dysfunction and dyssynchronous ventricular activation that provides simultaneous or nearly simultaneous electrical activation of the LV and right ventricle (RV) via stimulation of the LV and RV (biventricular pacing) or LV alone. This is performed by either a CRT-pacemaker (CRT-P) or by a combined CRT-implantable cardioverter-defibrillator (CRT-D). CRT devices include a transvenous pacing lead placed in a branch of the coronary sinus (or, less commonly, an epicardial or endocardial LV lead) for LV pacing, in addition to leads in the RV and right atrium. These leads are attached to a pulse generator typically located in the subcutaneous tissue of the upper chest. CRT involves pacing the left ventricle (LV) and usually simultaneous or nearly simultaneous pacing of the right ventricle to restore ventricular synchrony and thus improve LV systolic function and clinical outcomes for selected patients with LV systolic dysfunction and electrocardiographic evidence of electrical dyssynchrony. Indications for CRT for patients in sinus rhythm are based upon LV ejection fraction (LVEF), QRS duration, QRS morphology, New York Heart Association (NYHA) functional class, and need for ventricular pacing. The recommendations are predicated on a discussion with the patient about the risks and benefits of the procedure in the context of shared decision making.

心脏再同步治疗(CRT)是心脏起搏的一种方式,用于左心室(LV)收缩功能障碍和不同步心室激动的患者,通过LV的刺激提供LV和右心室(RV)的同时或几乎同时的电激活。 RV(双心室起搏)或单独LV。这由CRT起搏器(CRT-P)或组合的CRT植入式心律转复除颤器(CRT-D)执行。除了RV和右心房中的导联之外,CRT装置还包括放置在冠状窦分支(或不常见的心外膜或心内膜LV导联)中用于LV起搏的经静脉起搏导线。这些引线连接到通常位于上胸部的皮下组织中的脉冲发生器。 CRT涉及左心室起搏(LV)并且通常同时或几乎同时起搏右心室以恢复心室同步性,从而改善左室收缩功能障碍的LV收缩功能和临床结果以及电不同步的心电图证据。 窦性心律患者的CRT适应症基于LV射血分数(LVEF),QRS持续时间,QRS形态,纽约心脏协会(NYHA)功能分级以及心室起搏需求。这些建议基于与患者讨论在共同决策的背景下该程序的风险和益处。
