研究目的评价急性左室梗塞时右胸导联ST段抬高对合并右室梗塞的诊断意义。处理方法右胸导联(V_3R～V_5R)ST段抬高的界定为于J点后0.04秒处测量,自等电位线上移≥0.1mv被认为有意义。抬高类型参照Kataoka分类法。右室梗塞的诊断用非侵入性方法进行诊断。结果所研究的23例中,9例表现为右胸导联ST段抬高,其中3例符合右室梗塞的诊断标准,无右胸导联ST段抬高者14例,其中13例无右室梗塞表现,另1例不能确定。结论急性左室下壁梗塞时右胸导联ST段抬高对合并右室梗塞的诊断有重要价值。左室前壁梗塞时出现右胸导联ST段抬高,诊断合并右室梗塞需慎重分析。
Objective To evaluate the diagnostic value of right chest lead ST-segment elevation in the diagnosis of right ventricular infarction with acute left ventricular infarction. Approach The right chest lead (V_3R ~ V_5R) ST segment elevation defined as 0.04 seconds after the J point measurement, since the equipotential line shift ≥ 0.1mv is considered meaningful. The type of elevation refers to the Kataoka taxonomy. Diagnosis of right ventricular infarction is diagnosed by noninvasive methods. Results Of the 23 cases studied, 9 cases showed ST segment elevation of the right chest lead, 3 of them were diagnosed according to the criteria of right ventricular infarction. There was no ST segment elevation in right chest lead in 14 cases, of which 13 cases had no right Infarction performance, another case can not be determined. Conclusions ST segment elevation of the right chest lead during acute left ventricular inferior wall infarction is of great value in the diagnosis of right ventricular infarction. Right anterior chest lead ST-segment elevation appears in the anterior infarction of the left ventricle, diagnosis of right ventricular infarction need careful analysis.
