研究变时性功能不全患者（定义为运动心率反应未能升高到运动预期增加的两个标准差内），并与已知冠状动脉疾病患者（通过血管造影检查，有或无ST段压低）进行比较。
Patients with chronotropic incompetence, defined as a failure of the heart rate response to exercise to rise to within two standard deviations of the expected increase with exercise, were studied and compared to patients with known coronary disease by angiogram with and without ST segment depression.
