Variation in cumulative electrocardiographic depolarization (delta epsilon QRS) and repolarization (delta epsilon T and ST depression below 1 mm and more) parameters at threshold stress, achieved by stepwise augmentation, was compared with perfusion pressure in the left coronary arterial network, measured at coronaro-angiography, in 103 coronary patients. It is concluded that changes in cumulative ECG parameters at threshold stress can only be suggestive of a possible drop in perfusion pressure in the left coronary arterial network.
通过逐步增加负荷使103例冠心病患者达到阈强度运动时，对累积心电图去极化（δεQRS）和复极化（δεT以及ST段压低1mm及以上）参数的变化与冠状动脉造影时测量的左冠状动脉网络灌注压进行比较。得出的结论是，阈强度运动时累积心电图参数的变化仅提示左冠状动脉网络灌注压可能下降。
