【摘要】 目的:通过平板运动试验,增加心脏负荷,观察和分析冠心病心肌缺血的严重程度。方法:入选92例运动中和运动终止后有心绞痛发作13例,ST段下移41例,心绞痛伴ST段下移27例,U波倒置2例,运动后血压下降9例。结果:平板运动中心绞痛发作,ST段下移出现越早,ST段下移程度越大,持续时间越长,冠心病阳性率越高。运动性低血压,U波倒置也预示病人心功能不全。结论:提示平板运动试验可以预测冠心病心肌缺血的程度。更多还原

【Abstract】 Objective:To observating and analysising treadmill exercise test for increasing heart power stress,to predicating coronary artery disease serious extent in myocardial ischemia.Methods:92 cases during exercise test and after exercise test stopping,13 cases with attacking angina pectoris,41 cases with ST segment depression,27 cases attacking angina pectoris and ST segment depression,2cases with the downward U wave,9 cases with lower of systolic pressure.Results:During treadmill exercise test,the earlier angina pectoris attacks,the earlier and the deeper ST segment depression occurs,the longer ST segment depression lasts,the higher coronary artery positive rate.In addition,to predicating cardiac insufficiency for lower blood pressure and the downward U wave.Conclusion:To predicating of treadmill exercise test for coronary artery disease serious extent in myocardial ischemia.更多还原
