Abstract

In a patient with Wolff-Parkinson-White syndrome and an inferior-posterior bypass tract, transient restoration of normal conduction occurred during an attack of angina. The ECG pattern of inferior posterior ischemia was present when the conduction was normal. Thallium scintigraphy showed a reversible posterolateral perfusion defect. The possible mechanisms for production of intermittent preexcitation are discussed.

摘要

在一名患有 Wolff-Parkinson-White 综合征且存在下后壁旁路传导束的患者中，心绞痛发作期间出现了正常传导的短暂恢复。传导正常时存在下后壁心肌缺血的心电图表现。铊闪烁扫描显示后外侧灌注缺损可逆。文中讨论了产生间歇性预激的可能机制。
