摘　　要：目的探究经食管心脏电生理检查中心室起搏的可行性和安全性。方法回顾2012年1月至2017年6月经食管心脏电生理检查资料,分析心室起搏的发生率、导管放置深度、起搏的有效性和起搏阈值。结果 1617例受检者中,起搏心房组1 559(96.41%)例,起搏心室组58例(3.58%)。起搏心房组插管深度(40.02±1.39)mm,起搏阈值(15.18±3.83)V。起搏心室组插管深度(39.67±2.15)mm,起搏阈值(16.34±3.71)V。其中,心室起搏阈值大于心房起搏阈值,差异有统计学意义(t=-2.338,P<0.05)。心室起搏均为间歇性,多发生在长间期后,无法进行S_1S_1,S_1S_2程控心室起搏刺激。未发现因心室起搏诱发的心动过速。结论经食管心脏电生理检测中难以实施心室起搏。Objective To explore feasibility and safety of Transesophagealventricular pacing in transesophagealcardiac electrophysiological study. Methods The data of transesophageal cardiac electrophysiological study fromJanuary 2012 to June 2017 were used to analyze the incidence of ventricular pacing, the depth of esophageal catheter,effectiveness of pacing and pacing threshold. Results A total of 1617 persons underwent transesophageal cardiacelectrophysiological study. Of them, 1 559 cases underwent atrial pacing and 58 cases （3.58%） underwent ventricularpacing. The depth of esophageal catheter and pacing threshold were（40.02±1.39）mm and（15.18±3.83）V in atrial pacinggroup, （39.67±2.15）mm and （16.34±3.71）V in ventricular pacing group, respectively. There wasa significant differencebetween atrial and ventricular pacing thresholds（t=-2.338, P〈0.05）. Ventricular pacing was intermittent and most occurredafter a long R-R interval. It was failed to perform ventricularS1S1 andS1S2 programmed stimulation. No tachycardia wasinduced by ventricular pacing. Conclusion It is difficult to perform ventricular pacing during transesophageal cardiacelectrophysiological study.
