本研究要确定在稳定状态的平板运动时,精神刺激对冠心病患者的心率、收缩压、舒张压、血压-心率的乘积和氧摄取的作用。方法:研究对象为年龄自39岁到70岁的10名无高血压的冠心病患者。受试前休息10分钟;5分钟坐位,5分钟站在静止的活动平板上。此后受试者在无坡度的时速3英里的活动平板上走步。坡度每2分钟增加3.6度,直到受试者达到预计心率,即超过既往出现症状的最高心率的59%(±5次/分)。达
This study sought to determine the effect of psychostimulation on heart rate, systolic blood pressure, diastolic blood pressure, blood pressure-heart rate, and oxygen uptake during stable treadmill exercise. Methods: The subjects were 10 hypertensive coronary heart disease patients aged 39 to 70 years old. Rest 10 minutes before the test; 5 minutes sitting, 5 minutes standing on the stationary plate. Subjects then walked on a flat, 3-mile-per-day activity plate. The slope increased 3.6 degrees every 2 minutes until the subject reached the predicted heart rate, ie 59% (± 5 beats / min) of the highest heart rate for past symptoms. Up to
