摘要
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 article reported QTc interval (male 391.34±17.74 msec, female 402.60±20.13 msec, both<440 msec), JTc interval (male 312.12±19.35 msec, female 318.86±27.72 msec, both<360 msec) and QT/TQ rate (male 0.75±0.16, female 0.78±0.20, both<1.1) of 1309 healthy subjects. The above parameters were also studied in 181 patients with AMI, 25 patients with CRBBB or CLBBB. It was found that QTc interval and QT/TQ rate in AMI, CRBBB and CLBBB groups were longer or higher than those of normal group (p<0.01), however JTc interval was only longer in AMI group (p<0.01). It suggests that JTc interval could reflect myocardial repolarization state better than QTc and could be used in both normal or abnormal ventricular depolarization. In addition, better evaluation could be attained by determining JTc and QTc interval and QT/TQ rate simultaneously.
