摘　　要：为探讨JT及其变量与冠心病（CHD）的关系和最佳测量方法，我们对152例CHD患者和210例正常人（N），进行了不同电压、导联和性别间的JT、JTc、JTc／QTc值的比较分析。结果显示：CHD患者的JT及其变量可在常规心电图（1mV电压ECG）的Ⅱ或Ⅴ3导联进行测量和计算；CHD组JT及其变量的值均显著或极显著长于N组（P＜0.05～0．01），且女性显著或极显著长于男性（P＜0.05～0．01）。在除外其它因素的影响，JT及其变量的值在常规ECG中明显延长可作为诊断CHD的参考依据，并应注意女性长于男性的特点。由于JT间期能较准确地反映心室肌复极时间，且描记和计算方便，应大力提倡多用。The JT,JTc JTC/QTc in different sex,voltage and leads weremeasured in 152 patients with coranary heart disease(CHD) and 210normal control people in order to find the reationship between JT itsvariance and CHD as well as to find the best meaurement method.The results are as following: JTand its variance should be measured and calculated at lead II or V3 of regrular electrocardionram.Jt,JTc interval and JTc/QTc value in patients are significant longer than controls, while in females JT and its variance are longer that in males.This suggests that increased JT, JTc interval and JTc/QTc value can be reference in diagnosis of CHD.
