本文报道1 309名正常人的QTc间期(<440ms),JTc间期(<360ms)和QT/TQ比(<1.1),并与急性心肌梗塞(AMI)和单纯完全性左、右束支传导阻滞(CLBBB、CRBBB)患者对比,发现AMI、CLBBB、CRBBB患者QTc和QT/TQ比均明显大于正常组(P<0.01),而JTc间期仅AMI组显著长于正常组(P<0.01)。结果提示,JTc间期较QFc间期能更好地反映心室肌复极状态,对心室除极顺序正常和异常均适用。若能综合分析以上三值,对临床指导意义更大。
This paper reports the QTc interval (<440ms), the JTc interval (<360ms) and the QT / TQ ratio (<1.1) of 1 309 normal subjects and correlates with acute myocardial infarction (AMI) and simple complete left and right bundle branch The results showed that the QTc and QT / TQ of patients with AMI, CLBBB and CRBBB were significantly higher than those of the normal group (P <0.01), but only in the AMI group (P <0.01) ). The results suggest that, JTc interval QFc interval can better reflect ventricular repolarization, ventricular depolarization sequence is normal and abnormal are applicable. If a comprehensive analysis of the above three values, the clinical guidance of greater significance.
