摘要
房间传导阻滞（IAB；P波≥110ms）与左房（LA）扩大及电机械功能异常具有强相关性，是房性快速性心律失常（尤其是房颤）的强预测因素。虽然这些联系增加了血栓栓塞（即心源性卒中）的风险，但这一现象尚未被充分探讨。以2003年1月至2004年12月问因栓塞性卒中而入住综合医院神经科的85例患者为研究对象，对其中66例心电图示窦性心律者的IAB情况进行了评价，并将之分为有IAB者和无IAB者（对照）。然后回顾了这些患者的医疗记录以获得常见的并存病、卒中危险因素、高分辨率颈动脉多普勒超声检查报告以及此次因栓塞性卒中住院期间进行的二维超声心动图检查。
Interatrial block（IAB; P relate of left atrial （LA） e dysfunction and a strong wave t〉110 ms） is a potent cornlargement and electromechanical predictor of atrial tachyarrhythmias, in particular, atrial fibrillation. Although these associations increase its risk for embolism, i.e., cardioembolic stroke, such a phenomenon has been inadequately investigated. We investigated 85 general hospital patients who had been admitted to the neurologic unit between January 2003 and December 2004 for embolic stroke. Of those, 66 patients who had electrocardiograms that showed sinus rhythm were evaluated for IAB and categorized as those with IAB and those without（controls） Medical records were then reviewed for common co-morbidities and stroke risk factors, high-resolution carotid artery Doppler uhrasonographic study reports, and 2 -dimensional echocardiograms obtained during the current admission for embolic stroke;
