摘要 目的探讨罪犯血管对角支的急性心肌梗死病人心电图改变特点,总结诊断经验,以期为治疗提供依据。方法回顾性分析既往收治的40例心肌梗死病人临床资料,据罪犯血管分为左前降支组(25例)、对角支组(15例),对比两组12导联心电图,筛查具有价值的预测导联与预测值分布。结果两组病人性别、发病至送院时间差异无统计学意义(P>0.05);左前降支组病人年龄(68.3±8.1)岁,高于对角支组的(59.1±14.1)岁,差异具有统计学意义(P<0.05);对角支V5导联处T波段抬高幅度(0.05±0.13)mV,低于左前降支(0.03±0.13)mV,差异具有统计学意义(P<0.05),对角支组与左前降支组在aVI、V3、V4、V5导联处均值差值>0.03 mV或正负性相反;伴有aVI>0 mV、V3≤0.05 mV、V4<0或V5<0表现者为对角支病变风险比分别为1.39、1.48、2.22、4.44,同时伴有以上四项表现对角支梗死占46.67%,风险比11.67。结论 12导联可作为对角支心肌梗死与左前降支心肌梗死鉴别诊断工具,aVI、V3、V4、V5导联T波升降式鉴别诊断是重要依据。
