患者男性,42岁。因胸骨后剧烈疼痛6小时于1991年1月16日入院。患者20年前在部队体检时心电图发现Ⅱ、Ⅲ、aVFST段下斜型下移0.5～1mm,Ⅱ、Ⅲ、aVFT波倒置,V_(4～0)低平。然无胸痛、胸闷、心悸及晕厥等病史。嗣后每年心电图检查均无改变。曾先后到各地医院就诊未能确诊,亦未予以治疗。入院前1天晚卧床时(9时许)感胸前区隐痛,未予重视。至次日凌晨4时突然胸骨后压榨性剧烈疼痛,并向左肩部放散,伴头晕、恶心、全身冷汗。疼痛持续3小时无缓解,即来本院急诊。当时测血压20/12kPa,心电图示Ⅰ、aVL、V_(0～6)ST段抬高0.5～1mm;V_(2～4)ST段抬高2～4mm;Ⅲ、aVFST段下移0.5～1mm,Ⅱ、Ⅲ、
Male patient, 42 years old. Six hours after severe pain in the sternum was admitted on January 16, 1991. Twenty years ago, the electrocardiogram of the patients in the military examination showed that the downward slope of Ⅱ, Ⅲ and aVFST segments was 0.5 ~ 1mm. The Ⅱ, Ⅲ and aVFT waves were inverted and V_ (4 ~ 0) was flat. However, no chest pain, chest tightness, palpitations and syncope and other medical history. No subsequent ECG examination after each change. Have been to hospitals around the hospital failed to diagnose, nor to be treated. 1 day before admission when bed (9 o’clock) chest pain, no attention.
