| 摘 要： | 目的探讨平板运动试验中出现房间传导阻滞（IAB）的临床意义及机制。方法选择因胸闷、胸痛怀疑冠心病的患者69例，行平板运动试验及冠状动脉造影检查，按照运动试验中心电图P波时限的变化分为IAB组和无IAB组，比较两组患者的临床特征、平板试验中ST段最大下降程度和冠状动脉造影中冠状动脉狭窄程度和病变支数。结果①IAB组患者年龄高于无IAB组，（61．6±10．3）岁VS（56．8±8．9）岁（P=0．043）；②IAB组ST段最大下降≥1mm患者的比例高于无IAB组（80．5％VS48．5％，P=0．005）；ST段最大下降程度IAB组高于无IAB组，（1．78±1．45）mm VS（1．15±1．11）mm（P=0．047）；③冠状动脉造影中至少1支冠状动脉狭窄≥50％患者的比例，IAB组高于无IAB组（80．6％VS21．2％，P=0．001）；不同病变血管数患者的比例，两组间差异有统计学意义（P=0．006）。结论平板运动试验中出现IAB可能作为评价冠心病的辅助指标之一。 |

| Abstract: | Objective To investigate the clinical significance and mechanism of interatrial block(IAB) during treadmill exercise.Methods Sixty-nine patients with chest distress or chest pain were enrolled.They were arranged to perform treadmill exercise testing and P-wave duration was measured.The patients were divided into interatrial block group and non-interatrial block group according to the change of P-wave duration.Some clinical parameters and the degree of ST-segment depression during treadmill exercise test,and... |
