您要查找的是不是：
- The QRS duration and PR interval were measured at the electrocardiography speed of 50 milimeter per second. 左室舒张末期容积、射血分数和左室短轴缩短率显著提高;
- Cornell index needs a computer or a magnifying method to measure QRS duration and is difficult to application though it has relatively higher sensitivity than two other methods. Cornell指数敏感性提高,但方法繁琐,需要计算机检测或放大测量,且特异性较低,临床应用须积累更多经验。
- Only 105 (3.6%) patients who presented with a prolonged QRS duration at baseline had a normal QRS duration on their last electrocardiogram before hospital discharge. 只有105名（3.;6%25）QRS时限延长的患者在出院前的最后一次心电图检查QRS时限恢复正常。
- In comparing to normal sinus rhythm,the QRS duration was lengthened significantly when pacing at RVIS,RVOT or RVA(P<0.001). The QRS duration of RVIS pacing was shortened significantly as compared with that of RVOT and RVA pacing(P<0.001). 与正常窦性心律时QRS波时限比较;各部位起搏时QRS波时限均延长(P均<0.;001);其中RVIS起搏时QRS波时限延长程度最小;RVA起搏时延长程度最大;各部位两两比较P均<0
- In a small obserational study, CRT conferred significant clinical and entricular reerse-remodeling benefits regardless of QRS duration among patients with TDI-confirmed dyssynchrony. 一项小型观察性研究中，对TDI证实为心室运动失同步的患者行CRT，不论其QRS宽度如何，患者在临床症状和逆转心室重构方面均有显著好转。
