摘　　要：目的 通过总结感知自身R波后发放早搏刺激的RS_(2)、RS_(2)S_(3)、RS_(2)S_(3)S_(4)等RS系列程序刺激在经食管心脏电生理检查诱发及终止室上性心动过速(SVT)的成功率,探讨RS系列刺激在该检查中的应用价值。方法 回顾性收集2014年6月至2022年12月于广西医科大学第一附属医院行食管电生理检查及心内电生理检查诱发并诊断为SVT患者,统计包括RS系列刺激及S_(1)S_(1)、S_(1)S_(2)、S_(1)S_(2)S_(3)等多种刺激方式诱发和终止SVT的成功率。结果 共纳入325例患者,各RS刺激中,RS_(2)S_(3)S_(4)刺激方式在运动前、后对SVT的诱发成功率分别为47.52%和67.27%,运动前其诱发成功率与常用刺激方式(S_(1)S_(1)、S_(1)S_(2)、S_(1)S_(2)S_(3))无显著差异(P>0.05),运动后该刺激方式的诱发成功率优于S_(1)S_(2)(67.27%vs 25.76%,P<0.05)。采用RS_(2)、RS_(2)S_(3)及S_(1)S_(1)刺激终止SVT时,S_(1)S_(1)的终止成功率最高(95.35%),RS_(2)S_(3)终止成功率居其次(71.79%),RS_(2)终止成功率最低(47.34%),组间比较差异有显著性(P<0.001)。结论 RS系列刺激在经食管心脏电生理检查中具有重要的应用价值。Objective This study evaluates the efficacy of R wave-synchronized premature stimulation series(RS_(2),RS_(2)S_(3),RS_(2)S_(3)S_(4))during intrinsic rhythm for both inducing and terminating supraventricular tachycardia(SVT)in transesophageal electrophysiological studies,aiming to assess the utility of RS series stimulations.Methods We retrospectively analyzed data from 325patients diagnosed with SVT via transesophageal electrophysiological studies and intracardiac electrophysiological studies at the First Affiliated Hospital of Guangxi Medical University between June 2014and December 2022.We compared the success rates of different stimulation techniques,including RS series,in both inducing and terminating SVT.Results Among RS stimulations,RS_(2)S_(3)S_(4)showed pre-exercise and post-exercise induction success rates of 47.52%and 67.27%,respectively,with no significant difference from conventional methods(S_(1)S_(1),S_(1)S_(2),S_(1)S_(2)S_(3);P>0.05)pre-exercise,but superior post-exercise performance compared to S_(1)S_(2)(67.27%vs 25.76%,P<0.05).For SVT termination,S_(1)S_(1)had the highest success rate(95.35%),followed by RS_(2)S_(3)(71.79%)and RS_(2)(47.34%),with significant differences(P<0.001).Conclusion The RS series stimulations are highly valuable in transesophageal electrophysiological studies for both inducing and terminating SVT.
