平板(或踏车)运动心电图负荷试验在飞行人员医学鉴定中应用很广,习用的次极量平板运动试验在普通人群中冠心病诊断率可达80％以上,但对无症状飞行人员诊断率仅有21～25％,假阴性甚高,作者选择38例飞行人员“次极量”阳性或结果“异常”者,进行“极量”平板运动试验,探索对早期冠心病的诊断率可否提高。 对象和方法 1.对象:1978～1993年住院男性飞行员 Plate (or treadmill) exercise ECG load test is widely used in the medical identification of pilots, the conventional submaximal treadmill exercise test in the general population of coronary heart disease diagnosis rate of up to 80%, but the diagnosis of asymptomatic pilots Only 21 ~ 25%, false negative is very high, the author chose 38 flight crew “submaximal” positive or abnormal results, “extreme” treadmill exercise test to explore the early diagnosis of coronary heart disease can improve the rate of . Subjects and methods 1. Subjects: 1978 ~ 1993 hospitalized male pilots
