本文旨在:(1)根据接近极量的踏车运动试验、心绞痛病史和休息心电图,估计表面健康的中年男子中的隐性冠心病发病率。(2)探讨运动试验的某些其他方面能否用于鉴别真阳性及假阳性。方法:(1)对象:年龄40～59岁的挪威男性职工共2014名,均无已知的心、肺、肝、肾等疾病。(2)运动试验:先在运动前作卧位12导程心电图,踏车负荷开始为600千克/米(100瓦),以后每6分钟增加300千克/米,踏车速度近于60转/分。除非有特殊不适需
The purpose of this article is to: (1) Estimate the prevalence of implicit coronary heart disease in a healthy middle-aged man based on near-extreme treadmill exercise tests, angina history, and resting electrocardiogram. (2) Explore whether some other aspects of exercise testing can be used to identify true and false positives. Methods: (1) Subjects: A total of 2014 male workers from 40 to 59 years of age in Norway had no known diseases of heart, lung, liver and kidney. (2) exercise test: first before exercise in the lying position 12 lead ECG, treadmill load began to 600 kg / m (100 watts), after every 6 minutes to increase 300 kg / m, the speed of the car close to 60 rev / min .
