【摘要】 目的探讨急性心肌梗死(AMI)墓碑型心电图改变的临床意义。方法114例AMI患者入院后根据ST段抬高的类型分为2组:A组:ST段抬高呈墓碑型;共20例,B组:ST段抬高呈非墓碑型,包括弓背向上型、斜直型、新月型或平顶型,共94例,对比分析2组住院期间主要心脏不良事件的发生情况。结果A组ST段抬高AMI住院期间Ⅲ~Ⅳ级心功能患者、死亡率均超过B组(P<0.005)。心源性休克及急性左心衰的发生率也明显高于B组(P<0.005)。结论墓碑型ST段抬高AMI患者左心功能受损严重,泵衰竭发生率及死亡率高,临床预后差。ST段抬高呈斜直型、新月型或平顶型AMI临床预后相对较好。更多还原

【Abstract】 Objective To explore clinicial significance of "tombstoning" electrocardiographic pattern in patients with acute myocardial infarction.Methods 114 patients were divided into 2 groups according to ST segment elevation pattern:20 cases in group A showing "tombstoning" of ST segment elevation pattern and 94 patients in group B showing dome-shaped segment or scoope appearance or oblique straightening patterns.The major adverse cardiac event(MACE) was analyzed in the two groups.Results The baseline characteristics of the two groups were similar except that group A were almost anterior wall acute myocardial infarction.Patients of group A had a greater incidence of the left ventricular function failure(killip Ⅲ~Ⅳ) and death rate.Patients of group A had a greater incidence of cardiac shock.Conclusion There is significantly higher incidence of MACE in patients of "tombstoning"pattern.The left ventricular function decreases in patients with "tombstoning" electrocardiographic pattern.更多还原
