心电图对心律失常具有重要的诊断价值,而干扰脱节与隐匿性传导往往是造成复杂心律失常的原因之一,本文结合典型心电图改变,就这一问题予以简要的分析。一、干扰在心肌或传导系统发生兴奋后的一定时间内,对再来的强刺激不产生激动,称为绝对不应期。在绝对不应期之后的短时间内,如给以刺激,则可以发生兴奋但传导延缓,称为相对不应期。所谓干扰就是当心肌或传导系统发生除极之后,正处于绝对不应期时,对于继之而来的刺激不产生应激,也就是说激动受
ECG is an important diagnostic value of arrhythmia, and disruption of disruption and occult conduction is often caused by one of the causes of complex arrhythmia, combined with the typical ECG changes in this issue be briefly analyzed. First, the interference occurs in the myocardium or conduction system after a certain period of excitement, the strong stimulation of the return does not produce excitement, known as the absolute refractory period. In the short period after the absolute refractory period, if you give the stimulus, you can excited but conduction delay, known as the relative refractory period. The so-called interference is that when the myocardial or conduction system occurs after the depolarization, is in absolute refractory period, for the subsequent stimulation does not produce stress, that excited
