测量了68例完全性右或左束支传导阻滞患者的QT 间期和QRS 波群时间,并与QRS 时间正常的50份心电图对照。结果表明,观察组的校正QT 间期(QTc)较对照组明显延长,而两组之间的校正JT 间期(JTc)却无明显差异,说明束支传导阻滞患者的QT 间期延长是由QRS 波群增宽所致。文章同时着重探讨了JT 间期的校正方法。
Sixty-eight patients with complete right or left bundle branch block were measured for QT interval and QRS wave group time and compared with 50 ECGs with normal QRS duration. The results showed that the corrected QT interval (QTc) in the observation group was significantly longer than that in the control group, while there was no significant difference between the two groups in the corrected JT interval (JTc), indicating that QT prolongation in patients with bundle branch block was By the QRS wave group due to broaden. The article also focuses on the JT interval correction method.
