直接记录低振幅的窦房结(SAN)电位尚在研究之中,窦房传导时间(SACT)测定还只能用间接的方法。目前,临床多用1973年Strauss等提出的早搏刺激法(PAS)法,最近,Narula等又提出了一种更为简易的连续起搏法(CAP法)。为此,我们同时用两种方法测定SACT26例以进行两种方法的比较。 Direct recording of low amplitude sinus node (SAN) potentials is still under investigation, and SNA determination can only be used in indirect methods. At present, the clinical application of pre-stimulation stimulation (PAS) method proposed by Strauss et al. In 1973 has been more and more recently, Narula et al proposed a more simple continuous pacing method (CAP method). To this end, we used both methods to determine SACT26 cases to compare the two methods.
