Exercise electrocardiography detection of coronary artery disease by ST-segment depression/heart rate hysteresis in women: the Finnish Cardiovascular Study.

Introduction: The performance of exercise electrocardiography (ECG) for the detection of coronary artery disease (CAD) in women has been limited. The recently developed computerized variable, ST-segment depression/heart rate (ST/HR) hysteresis, has been proved to detect CAD in men more accurately than traditional methods. However, the diagnostic performance of ST/HR hysteresis has not been evaluated in women.
