经食道左心房起搏,简称食道起搏(EsoP)是一种非创伤性方法。自1952年应用以来,由于局部刺激重和可靠性问题,临床应用受到限制。近年来随着刺激器、导管电极和记录方法的改进,其应用范围不断扩大。基于EsoP和经静脉右心房起搏(RAP)的对比观察资料不多,本文在完全相同的条件下,比较EsoP和RAP两种方法对评定窦房结功能的价值;并用心内膜标测技术观察二种方法起搏后的心内传导途经和传导时间的差异,以探讨EsoP的临床应用价值。
Transanal left atrial pacing, referred to as esophageal pacing (EsoP) is a non-invasive method. Since its application in 1952, its clinical application has been limited due to the localized irritation and reliability issues. In recent years, with the stimulator, catheter electrodes and recording methods improved, its scope of application continues to expand. EsoP and transvenous right atrial pacing (RAP) based on the comparative observation of the data is not much, this article in exactly the same conditions, the EsoP and RAP two methods to evaluate the value of sinoatrial node function; and endocardial mapping technology To observe the difference of intracardiac conduction pathways and conduction time between the two methods in order to explore the clinical value of EsoP.
