【摘要】 目的探讨前壁急性心肌梗死(AMI)合并J波的临床特点。方法对近年住院的94例前壁AMI者的心电图进行回顾性分析,观察出现J波者与无J波者的冠脉造影(CAG)结果、二度Ⅱ型和/或三度房室阻滞、室性心律失常、临床症状、并发症的发生率。结果有J波组(A组)冠脉狭窄程度重于无J波组(B组)(P<0.025);多支冠脉病变A组发生率高于B组(P<0.05)、二度Ⅱ型和/或三度房室阻滞发生率明显高于B组(P<0.005)、A组并发症发生率高于B组(P<0.025)、室性心律失常的发生率A组高于B组(P<0.05);临床症状A组较B组严重(P<0.025)。结论前壁AMI者心电图出现J波者病情较重,缺血性J波也是恶性心律失常的预警指示。更多还原

【Abstract】 Objective To evaluate the clinical characteristics of acute anterior myocardial infarction with J wave.Methods The ECG data were analyzed retrospectively in 94 patients with acute anterior myocardial infarction(AAMI).To evaluate the following characteristics of the AAMI with J wave (Group A)and that without J wave (Group B):the result of coronary angiography,second degree type Ⅱand/or third degree atrioventricular block ,ventricular arrhythmia,general conditions and complications.Results The data showed that the coronary Group A was narrower than that of Group B (P<0.025); the following indices in Group A were higher than those of Group B:multi-vessel coronary artery disease(P<0.05),second degree type Ⅱand/or third degree atrioventricular block(P<0.005),complications(P<0.025) and ventricular arrhythmia (P<0.05).Clinical symptoms of Group A were more serious than that of Group B (P<0.025).Conclusion The state of the illness in acute anterior myocardial infarction with J wave are more serious.Ischemic J wave is an effective index in predicting malignant ventricular arrhythmia.更多还原
