摘要
目的 探讨食管心房调搏 (TEAP)对阵发性室上性心动过速 (PSVT)的诊断价值。 方法 对 12 6例阵发性室上性心动过速的食管与心内电生理检查 (EPS)结果进行分析。 结果 ①检出室上性心动过速 12 6例 (诊断阳性率 10 0 % )。②房室结折返性心动过速 (AVNRT) 5 2例 (阳性率 92 4 % ) ;房室折返性心动过速 (AVRT)72例 ;单旁路 70例 (阳性率 10 0 % ) ;双旁路 2例 (准确率 5 0 % )。 结论 食管心房调搏能够确诊大部分阵发性室上性心动过速的性质及发生部位 ,与心内电生理检查具有高度的一致性 。
Objective To investigate diagnostic value of transesophageal atrial pacing for PSVT. Methods Analyze the results of TEAP and EPS in 126 cases of patients with PSVT.Results (1)126 cases of PSVT(100%) (2) 72 cases of Atrial-ventricular reentrant tachycardia(AVRT),52 cases(92.4%)of Atrial-ventricular node reentrant tachycardia(AVNRT),70 patients with single accessory pathway(AP)(100%),and 2 cases with dual AP (50%).Characteristics and position of PSVT can be definitely diagnosed by transesophageal atrial pacing.The result on PSVT by esophageal electrophysiological investigation could be as high accurate as that of intracardiac electrophysiology.Conclusion Esophageal pacing was a reliable means for distinguishing mechanism of supraventricular tachycardia and location in radiofrequency catheter ablation.
