食管心房调搏与阿托品检测房室交接区传导分析

The Analysis of the Application for Transesophageal Atrial Pacing Combined with Atropine in the Atrioventricular Junctions Conduction Testing

目的探讨食管心房调搏联合应用阿托品在房室交接区传导功能检测中的价值。方法选取2011年5月-2012年9月在梅州市人民医院检测房室交接区传导功能的72例患者资料进行回顾性分析,分析其中的阳性率情况。结果测定房室传导阻滞点静注阿托品前调搏2∶1房室传导阻滞点<150次/min阳性率为71.4%,静注后25.4%;一度房室传导阻滞点<100次/min静注前阳性率95.2%,静注后31.7%;二度I型房室传导阻滞组静注前阳性率77.8%,静注后41.7%,比较静注前后的阳性率差异有统计学意义,P<0.05。结论食管心房调搏联合阿托品检测房室交接区传导功能可降低假阳性的发生率,提高临床效果。

Objective To investigate the value of transesophageal atrial pacing combined with atropine in the atrioventricular junctions conduction testing.Methods The clinical data of 72 cases with the detection of atrioventricular junctions conduction from May 2011 to September 2012 were taken for retrospective analysis.They were taken with esophageal law the atrial pacing joint atropine for detection and the positive rate was analyzed.Results The positive rate for determination of atrioventricular block points intravenous atropine pacing 2∶ 1 atrioventricular block point 150 beats / min was 71.4 % and 25.4% after intravenous injection.The positive rate for once atrioventricular block point 100 beats / minintravenously was 95.2% and 31.7% after intravenous injection.The positive rate of second degree type I atrioventricular conduction block group intravenous was 77.8%,and 41.7% after intravenous injection.The differences for the positive rate before and after intravenous were significant,with P〈0.05,there was statistical significance.Conclusion The transesophageal atrial pacing combined with atropine can reduce the incidence of atrioventricular junctions conduction function,and improve the clinical outcomes.
