房室结(AVN)及希浦系(HPS)不应期是反映房室传导功能的一个重要指标,它在检查房室结病变,研究药物的药理作用及探讨某些心律失常的发生机制等方面均具有重要意义。国外测定AVN及HPS不应期均采用经静脉心房调搏法,我们自1981年10月起探索性地采用经食道心房程序式额外刺激法对80例病人测定了AVN-HPS不应期,初步看来对于了解房室传导系统的病变有一定的临床实用价值。现将检查方法及结果报道如下。
Atrioventricular nodal (AVN) and Hippocampus (HPS) refractory period is an important indicator of atrioventricular conduction, it is in the examination of atrioventricular node disease, study the pharmacological effects of drugs and explore the mechanism of some arrhythmias All aspects are of great significance. Foreign measurement of AVN and HPS refractory period using intravenous atrial pacing method, we have explored since October 1981 with the esophageal atrial procedures additional stimulation method for the determination of 80 cases of AVN-HPS refractory period, preliminary It seems that there is a certain clinical value for the understanding of atrioventricular conduction system lesions. The inspection methods and results are reported below.
