目的:分析超急性期ST段抬高型心肌梗死(STEMI)病人的心电图特征。方法:回顾性分析45例超急性STEMI患者的心电图检查结果。结果:本组超急性STEMI患者中,急性下壁5例(11.11%),急性前壁并下壁2例(4.44%);急性前壁侧壁8例(17.78%);急性前壁18例(40.00%),前间壁12例(26.67%)。缺血性J波16例(35.56%),无J波29例(64.44%)。有J波组室性心律失常的发生率为68.75%,显著高于无J波组的37.93%(P<0.05)。结论:心电图在超急性STEMI的诊断中具有重要的应用价值,它可以提示出患者疾病的特征表现,为进一步诊断及预防室性心律失常提供了有效的参考。
Objective: To analyze the electrocardiographic features of hyperacute STEMI patients. Methods: The ECG findings of 45 patients with hyperacute STEMI were retrospectively analyzed. Results: In this group of patients with acute STEMI, acute inferior wall in 5 cases (11.11%), acute anterior wall and inferior wall in 2 cases (4.44%); acute anterior wall in 8 cases (17.78%); acute anterior wall in 18 cases (40.00%), anterior wall in 12 cases (26.67%). 16 cases of ischemic J wave (35.56%), 29 cases without J wave (64.44%). The incidence of ventricular arrhythmia in J wave group was 68.75%, which was significantly higher than that in non-J wave group (37.93%, P <0.05). Conclusion: ECG is of great value in the diagnosis of hyperacute STEMI. It can indicate the characteristic of disease in patients and provide an effective reference for further diagnosis and prevention of ventricular arrhythmia.
