  《国际循环》：窄QRS波和仅存在机械不同步的患者常常让医生非常困扰，没有证据证明此类患者从CRT治疗中获益。在这个问题上，这次是否有让我们惊喜的结果？

    Prof Vardas: Patients with narrow QRS [ ]and mechanical dyssynchrony are not represnted as class 1 according to the ESC guidelines. However， there have been a few published papers including one in the New England Journal of Medicine; indicating that in well selected cases with narrow QRS and mechanical dyssynchrony CRT can be beneficial.
