多年以来,对T波变化的性质一直认为只有原发性和继发性二类.继发性T波变化由激动程序的改变引起,原发性变化与心室梯度的改变有关.本文研究说明,心室激动程序的改变也可引起兴奋状态时限的变化,从而改变心室梯度,引起原发性T波异常;亦即,心室除极调整了心室复极的次序,而且这种调整具有累积和储存的性质.作者分析了左束支阻滞(自发的或心房调搏后)及右心室调搏后的各种心电图变化,显示了二种在
Over the years, the nature of the T-wave changes has been considered only the primary and secondary categories.Secondary T-wave changes caused by changes in the activation program, the primary changes in the ventricular gradient changes.This study shows that, Changes in the ventricular activation program can also cause changes in the timing of the state of excitement, thereby changing the ventricular gradient and causing primary T wave abnormalities; that is, ventricular depolarization adjusts the order of ventricular repolarization and this adjustment has the effect of accumulating and storing Nature of the author analyzed the left bundle branch block (spontaneous or after atrial pacing) and right ventricular pacing after a variety of ECG showed two kinds of
