运动试验时常有室上性期前收缩出现,但其 ST 段下移的意义却未见报道。这促使我们对运动诱发室上性期前收缩和前一窦性搏动 ST 段下移以及两者差与冠心病(CAD)的关系进行了研究。方法在2200例可疑或确诊 CAD 患者的活动平板运动试验中检出室上性期前收缩486例(22.1%),其中133例做过左室和冠状动脉造影;男101、女32例,年龄30～67(平均53.5±7.9)岁。明确 CAD 者96例为
Exercise tests often have supraventricular systolic, but the significance of its ST segment down has not been reported. This prompted us to investigate the relationship between exercise-induced supraventricular premature supraventricular tachycardia and previous ST segment depression of sinus beats and their association with coronary heart disease (CAD). Methods Twenty-eight cases (22.1%) of supraventricular seizures were detected during active treadmill exercise test in 2200 patients with suspicious or confirmed CAD. 133 cases had left ventricular and coronary angiography; 101 males and 32 females, aged 30 ~ 67 (average 53.5 ± 7.9) years old. 96 cases of clear CAD
