房室结与希氏束区域的起搏点位于何处,有很大争论,曾被提到的位置有五处:冠状窦开口,房室结的上部(AN)、中部(N)和下部(NH),以及希氏束。虽有大量证据说明房室结具有自律性,但近年来的一些研究认为房室结没有自律性,所谓的“结性心律”实源自心房下部或希氏束。由于这方面的分歧尚未解决,故在名词上予以折衷,统称为“连接处性心律”。本文根据实验与临床观察资料,提出对“连接处性心律”的分类意见。房室连接处的微电极记录:房室结和希氏束的电生理学与药理学特性有所不同。房
There are many controversies about where the atrioventricular node and His bundle tract are located. There have been five locations mentioned: the coronary sinus opening, the upper part (AN), the middle part (N) and the lower part of the atrioventricular node (NH), and His bundle. Although there is a lot of evidence that atrioventricular node with self-discipline, but in recent years, some studies believe that atrioventricular node does not self-discipline, the so-called \"nodal rhythm\" is actually derived from the atrium or His bundle. Because of the differences in this area have not yet been resolved, it is compromised in the terms, collectively referred to as the \"connection of the heart rhythm.\" Based on the experimental and clinical observation data, this article puts forward the classification opinion on the \"connecting ventricular rhythm\". Microelectrode recording at atrioventricular junction: The electrophysiological and pharmacological properties of the atrioventricular node and His bundle are different. room
