摘要
本文报告34例冠状动脉造影患者常规心电图与头胸导联心电图(HC)对比分析结果。冠脉狭窄21例(61%).心肌梗塞(MI)9例.狭窄75%以上占87.5%。非 MI 狭窄37.9%(P<0.01)。5例右室 MI 和左右壁 MIHC 导联全部检出,常规导联仅检出2.5例。高侧壁MIHC 导联 CL 软 avL 定位准确。对前壁和下壁 MIHC 导联并不优于常规导联。结果也提示,冠脉狭窄大于50%两种导联心电图才出现有意义改变。
Coronary antrogroyraphy (CAG)was compared with Conuentional ECG (ECG) and head chest (HC) ECG in 34 patients with cardiac disease.In 21 cases of coronarg structure (e61%),9 cases of myocardial infarction (MI) coronary Structure,even obstruetion,more than 75% were87.5%,but 37.9% withoat MI (P<0.01).Au 5 cases of right nentricular and left posterior wall MI were detectived,ECG2.5 cases only.MI in high lateral wall localization cL in HC is more than avL.Both channals had no quite diffcrence in anterior and inferior wall MI.About the relations of ECG and coronary straeture,in the cases without MI,it was signifi eant if the lesien more than 50%.
