三种心脏负荷试验对冠心病诊断价值的对比研究

Comparable study of 3 cardiac loading tests on the diagnosis of coronary heart disease

目的：探讨食管心房调搏负荷试验、平板试验、潘生丁试验对冠心病的诊断价值。方法：食管心房调搏负荷试验、活动平板试验，心率达到次极量级水平，按二阶梯运动试验的方法记录心电图。潘生丁试验，潘生丁0．50～0．75mg/kg溶于5％葡萄糖液20ml中，前3min注入总量的一半、后7min注完另一半。结果：三种方法的敏感性分别为84．6％、76．9％、69．2％，特异性分别为100％、100％、95％。结论：食管心房调搏负荷试验优于活动平板试验和潘生丁试验。

Objective:To find out diagnosis values of atrial pecing test,treadmill exercise test,dipyridamol test on the coronary heart disease. Methods:When heart rate achieved the level of submaximal exercise test according to Master's method, electrocardiogram was recorded in atrial pacing test and treadmill exercise test. In dipyridamol test,dissolved dipyridamol 0. 5~0.75 mg/kg in 5% glucose 20 ml.Injected 1/2 dosage of dipyridamol within first 3 minutes,the other 1/2 dosage of dipyridamol was completely injected in 7 other minutes. Results:Sensitivity of 3 cardiac loading test was respectively 84.6 %, 76.9 %, 69.2 %,specificity was respectively 100%, 100%, 95%. Conclusions:Diagnostic value of atrial pacing test superior to other 2 cardiac loading tests.
