methods:analyses the data of electrocardiogram with or without st-segments depression on precordial leads of 32 patients with aimi and compared with cardiac function and coronary angiogram.
方法:对32例aimi患者的心电图是否有胸前导联st段下降与心功能分级和冠状动脉造影资料进行对比分析。
objective: to explain the physiologic electric phenomena of acute inferior myocardial infarction accompanied with st depression in precordial leads with body surface potential mapping (bspm).
目的用st段体表等电势图(bspm)的方法解释急性下壁心梗伴有胸导联st段下移的心电现象。
atrial wave in precordial leads had not any change.
胸前导联心房波无明显变化。
results:the magnitude of st segment elevation in inferior wall leads was significantly negatively correlated with that of precordial leads in acute inferior wall myocardial infarction (all p0 01).
结果:急性下壁心肌梗死时心电图下壁导联st段抬高幅度与胸前导联st段改变均呈负相关(p均0 .0 1 )。
