摘要
房室折返性心动过速时,心房激动的顺序对预激综合征患者房室旁道的定位非常重要。本文通过比较经右胸壁记录的右房电位和经食管记录的左房电位,大致能将游离壁旁路和间隔旁路区分开来。本组无创性房室旁路定位诊断均经心内电生理检查加以证实。
Atrial activation sequence during atrioventricular reciprocating tachycardia is very important in localizing atrioventricular bypass tracts (AVBTs) of patients with Wolff-Parkinson-White syndrome. By comparing right atrial potential recorded on the right anterior chest wall with left atrial potential recorded from the esophagus, we could roughly distinguish free-wall and septal AVBTs. The results of noninvasive location of the AVBTs have been confirmed by intracardisc electrophysiologic studies.
