The Q-Tc interval before and after the treadmill exercise test in 48 normal subjects and 59 patients with coronary heart disease were compared. The Q-Tc interval was shorter in normal group at immediate moment, 2, 4 and 6 minutes after the exercise than before. In the coronary heart disease group, the Q-Tc interval at the same time points as above was longer after exercise compared to pre-exercise. There was no significant difference of exercise-induced Q-Tc changes in silent and symptomatic myocardial ischemia.
比较了48名正常受试者和59名冠心病患者在平板运动试验前后的QTc间期。正常组在运动即刻、运动后2分钟、4分钟和6分钟时的QTc间期比运动前短。在冠心病组中，与运动前相比，上述相同时间点运动后的QTc间期更长。无症状性和有症状性心肌缺血患者运动诱导的QTc变化无显著差异。
