摘要(Abstract):

用经食道心房调搏(TEAP),检测103例心律失常病人,检出房室结双径传导(DAVP)13例(12.6%),其中15例有阵发性室上性心动过速史(PSVT),检出 DAYP10例(66.7%),88例无 PSVT 史,仅检出 DAVP 3例(0.03%)。11例显出不连续房室传导时间(SR)曲线,经快通道(FP)传导的 SR 间期(SRFP)为191.54±32.9ms,经慢通道(SP)传导的 SR 间期(SPsp)为319.23±60.1ms。本文提示 TEAP 可无创性诊断DAVP。
Evidence of dual atrioventricular nodal pathways(DAVP)was shown in 13(12.6%) out of 103 patients studied by transesophageal atrial pacing tech- niques.Among the 15 cases with paroxysmal supraventricular tachycardia (PSVT),10cases(66.7%)with DAVP were found by transesophageal atrial pacing. The discontinuity in A-V conduction curve was demonstrated in 11 cases and the atypical Wenckebach phenomenon was found in 1 case.The conduction time through fast and slow pathways were 191.5±32.9ms,319.2±60.1ms respe- ctively.The PSVT may be initiated and terminated with atrial stimulation. it has proved that transesophageal atrial pacing is an important noninvasive method to demonstrate DAVP.
