摘　　要：①目的　探讨经食管心室起搏的临床应用效果。②方法　随机选择行电生理检查的病人 6 9例 ,采用自行设计的导电球囊电极导管进行经食管心室起搏 ,并与普通金属环电极导管起搏结果进行比较。③结果　应用导电球囊电极导管起搏的 6 9例中 6 7例顺利完成经食管心室起搏检查 ,成功率 97.1% ,平均起搏电压 (2 3.6 8± 3.95 )V。应用普通金属环电极导管起搏 4 1例成功 ,成功率 5 9.4 % ,平均起搏电压 (38.6 7± 1.2 8)V。两种导管起搏电压比较差异有显著意义 (t=2 5 .0 6 ,P <0 .0 1) ,两种方法的成功率比较差异有显著意义 (χ2 =5 5 .5 6 ,P <0 .0 1)。④结论　应用导电球囊电极导管心室起搏较普通金属环电极起搏具有成功率高、起搏电压低等优点。Objective\ To study the effect of transesophageal ventricular pacing by using an electric balloon electrod. Methods\ With a self made electric balloon electrode, 69 patients underwent transesophageal ventricular pacing. The results were compared with those of ordinary loop electrode.\ Results\ Transesophageal ventricular pacing were performed successfully in 67 cases (97.1%). The average volt was (23.68±3.95)V. The success rate and average volt in the cases with ordinary loop electrode were 59.4% and (38.67±1.28)V, respectively. The difference between the two groups was significant ( t=25.06,P<0.01; χ 2=55.56,P <0.01). \ Conclusion\ Ransesophageal ventricular pacing with electric balloon electrode has higher success rate and lower voltage than that with ordinary loop electrode.
