Abstract

Cardiac resynchronization therapy (CRT) is beneficial for a majority of patients with medically refractory heart failure due to severe left ventricular (LV) systolic dysfunction and prolonged interventricular conduction to improve symptoms and LV performance. An optimally programmed atrioventricular delay (AVD) during CRT can be also important to maximize the response in left ventricular function. Several Doppler echocardiographic methods have been reported to be useful for determination of the optimal AVD. This review will discuss the various Doppler-based approaches to program the AVD in patients that receive CRT.

摘要

心脏再同步治疗(CRT)对大多数因严重左心室(LV)收缩功能障碍和心室间传导延长而药物治疗难治性心力衰竭的患者有益,可改善症状和左心室功能。CRT期间优化程控的房室延迟(AVD)对于使左心室功能反应最大化也可能很重要。据报道,几种多普勒超声心动图方法有助于确定最佳AVD。本综述将讨论在接受CRT的患者中程控AVD的各种基于多普勒的方法。
