多年来人们一直在探索评价冠心病的无创伤性检查方法,其中平板运动心电图负荷试验及踏车运动试验已获国际公认并推广使用,但因运动量大,有其局限性。本文提出用食道调博法使心率达到亚极量负荷标准的心电图负荷试验(下称调搏负荷),并通过对94例冠心病及正常人的对比,进行方法学研究及评价。临床资料及方法一、对象: 94例受试者中,经心内科临床确诊的冠心病患者57例(男47例,女10例),年龄47～74岁,均无电解质紊乱,亦未使用洋地黄制剂。受试前一周停用扩血管药物及β—阻滞剂。对 Over the years people have been exploring the evaluation of noninvasive coronary heart disease testing methods, including treadmill exercise ECG test and treadmill exercise test has been internationally recognized and promote the use, but because of exercise, has its limitations. This paper presents the use of esophageal Bo method so that the heart rate reached sub-load standard ECG load test (hereinafter referred to pacing load), and by comparison of 94 cases of coronary heart disease and normal subjects, methodological studies and evaluation. Clinical data and methods 1. Subjects: Of the 94 subjects, 57 patients (47 males and 10 females) with coronary heart disease diagnosed clinically and psychologically were aged 47-74 years without electrolyte imbalance and were not used Digitalis preparations. One week before the test vasodilators and beta-blockers were discontinued. Correct
