QRS波时限预测心脏再同步治疗反应价值的研究进展

Value of QRS duration predicting response of cardiac resynchronization therapy.

目前心脏再同步治疗(CRT)患者主要是根据体表心电图QRS波时限来判断是否存在心脏的不同步。但是临床上心脏的机械收缩不同步与电不同步之间并非完全相关。少数QRS波时限明显增宽患者,并不存在机械收缩的不同步,而部分QRS波时限不增宽的患者,却存在机械收缩的不同步。明确心脏是否存在机械不同步,或许能减少CRT无应答。本文关于QRS波时限预测心脏再同步治疗存在的价值进行综述,进一步探讨QRS波时限对CRT治疗的影响。

QRS wave duration is a main method of deciding cardiac asynchrony in patients with Cardiac resynchronization therapy （CRT）. But cardiac mechanical dyssynchrony was not always consistent with electrical dyssynchrony. A few patients with widened QRS wave duration had not the cardiac mechanical asynchrony, while some patients with normal QRS Wave duration had cardiac mechanical asynchrony. If the cardiac mechanical dyssynchrony was determined, it would be possible to reduce the non-response of CRT. We review the role of QRS duration to predicting the prognosis of CRT and debate the effect of QRS duration to CRT.
