摘　　要：目的 :探讨胸痛时心电图心前导联 ST段压低在急性后壁心肌梗死中的临床意义。方法 :4 2例持续性胸痛超过 30 min患者常规做 12导联心电图 ,每隔 4 h做 1次 ,2 4 h后每天做 1次 ,当 V1 ～ V3导联 ST段压低时加做 V7～ V9导联 ,同时测心肌酶。结果 :胸痛时心电图 V1 ～ V3导联 ST段压低可能是急性后壁心肌梗死早期表现。结论 :对这类患者应常规加做 V7～V9导联 ,以利早期诊断。Objective Tive To explore clinical significance of on chest ST segmentdepression in leads V 1~V 3 at acute posterior wall myocardial infarctionduring chest pain.Methods ECG in 12 leads was routine done in 42 cases patients fourhours a time after admission and every day a time after 24 hours.When STSegment depression in leads V 1~V 3,ECG in leads V 7~V 9 was done inaddition.Results ST segmentdepression in leads V 1~V 3 during chest pain was a early manifestat atacute Mol wall myocardial infarction.Conclusion ECG in leads V 7~V 9,should be routine done for thesepatients.
