A treadmill exercise test response may become positive because a diagnostic electrocardiographic ST-segment shift occurred during exercise, or, less often, because it occurred only during the recovery period after exercise had been completed. Factors that may be related to these 2 different responses in subjects enrolled in the Program of Surgical Control of Hyperlipidemia were investigated. No differences were found with regard to age, sex, level or location of Minnesota electrocardiographic Q-QS codes, number of narrowed coronary arteries, presence of collateral coronary artery circulation, ejection fraction, number of abnormally moving left ventricular wall segments, heart rate, systolic and diastolic blood pressure, double product, total exercise time, exercise-induced angina, or maximally achieved exercise heart rate or double product. Thus, the same significance should be attributed to a recovery-positive as to an exercise-positive treadmill test, and electrocardiographic, hemodynamic and angiocardiographic variables do not distinguish between subjects who exhibit these 2 different responses.
跑步机运动试验反应可能会呈阳性，原因是运动期间出现了诊断性心电图ST段移位，或者较少见的情况是，仅在运动完成后的恢复期出现了这种移位。对参加高脂血症外科治疗项目的受试者中可能与这两种不同反应相关的因素进行了研究。在年龄、性别、明尼苏达心电图Q-QS编码的水平或位置、冠状动脉狭窄数量、冠状动脉侧支循环的存在、射血分数、左心室壁异常运动节段的数量、心率、收缩压和舒张压、乘积、总运动时间、运动诱发的心绞痛，或最大运动心率或乘积方面未发现差异。因此，恢复阳性的跑步机试验与运动阳性的跑步机试验应具有相同的意义，并且心电图、血流动力学和心血管造影变量无法区分表现出这两种不同反应的受试者。
