5、12导联ECG;Ⅱ,Ⅲ和avF导联至少有2个导联ST段抬高大于或等于1mm;血清心肌酶:磷酸肌酸激酶同功酶(CK-MB)峰值大于正常的2倍以上.同时排除合并前间壁、前壁、侧壁心肌梗死患者.以入院时床边常规12导联ECGⅢ和Ⅱ导联ST段抬高程度分为两组:A组(STⅢSTⅡ)39(男30,女9)例,年龄39~75(平均64)岁;B组(STⅡSTⅢ)8(男7,女1)例,年龄50~80(平均65)岁.1.2方法所有患者入院后即入CCU病房,持续心电血压监护3~5d,发病后3d内每6~8h测血清磷酸肌酸激酶同工酶(CK-MB)1次,取其峰值作为心肌坏死范围的估计值[8].所有患者在入院后的1~
6、7d行冠状动脉造影(CAG)检查,部分病例行PTCA或支架置入术.右室梗死患者加做V3R,V4R,V5R导联.右室梗死的诊断依据为:急性下壁心肌梗死的心电图表现,颈静脉怒张伴低血压或休克等右心功能不全征象,双肺底无湿性罗音;超声心动图或右室造影提示右室壁运动减弱.根据CAG将右冠状动脉(RCA)分为3段:RCA起始部至圆锥支为近段,圆锥支至锐缘支为中段,锐缘支以下为远段.记录住院4yocardialinfarction[J].Di-siJunyiDaxueXuebao(JFourthMilMedUniv),2001;22(21):1949-1952.[2]GuoilMedUniv),
