平板运动试验变时性不全对冠心病诊断价值分析

Analysis for Chronotropic Incompetence During Treadmill Exercise Testing To Diagnosis Coronary Heart Disease

目的对照平板运动试验与冠状动脉造影结果,探讨平板运动试验心脏变时性不全对冠心病诊断的价值。方法在行平板运动试验检查者中选择资料完整的行平板运动试验与冠状动脉造影的患者进行结果对照,观察运动引起心脏变时性不全与冠状动脉造影之间的联系,并与ST段压低诊断冠心病相比较。结果846例平板运动试验中有6例心脏变时性不全,并且冠状动脉造影均阳性。结论在平板运动试验中心脏变时性不全可以准确诊断冠心病,并且较ST段压低更加敏感。

Objective Discuss chronotropic incompetence during treadmill exercise testing to direct coronary heart disease （CAD） diagnosis value through treadmill exercise testing and coronary angiography. Methods Select patients with usefull date as treadmill exercise testing and coronary angiography （CAG）,search the relation between chronotropic incompetence in exercise testing and CAG,and more compared with ST Segment depress. Results 6 patients had chronotropic incompetence in exercise testing,all of these 6 patients had positive result for coronary angiography.Conclusion Chronotropic incompetence during treadmill exercise testing to diagnosis coronary heart disease was a effect method, and was more sensitive than ST segment depress.
