摘要
目的探讨急性下壁心肌梗死伴胸导联ST段压低的临床意义。方法观察64例急性下壁心肌梗死胸导联ST段压低与常规及24h动态心电图检查结果的关系。结果①单纯下壁心肌梗死不伴胸导联ST段改变显著多于伴胸导联ST段改变(P<0.01),下壁伴正后壁心肌梗死伴胸导联ST段改变显著多于不伴胸导联ST段改变(P<0.01),而下壁伴右心室心肌梗死与胸导联ST段改变无明显区别(P>0.05)。②伴胸导联ST段改变者严重室性心律失常与房室传导阻滞的发生率均较不伴胸导联ST段改变者高(P<0.05)。结论急性下壁心肌梗死伴胸导联ST段压低表明心肌梗死广泛,严重室性心律失常和房室传导阻滞的发生率明显增多。
Objective To discuss clinical significance about Inferior wall acute myocardial infarction with descent of chest lead ST segment. Methods Sixty four patients with inferior wall acute myocardial infarction were observed, including changes of chest lead ST segment, routine electrocardiogram and 24 hours dynamic electrocardiogram. Results ①Thirty six patients with no chest lead ST segment descent and 28 patients with chest lead ST segment descent were observed, amount of patients suffering from single inferior wall acute myocardial infarction with no chest lead ST segment descent were far more than that of patients with chest lead ST segment descent (P <0.01), percent of patients suffering from inferior wall and behind wall acute myocardial infarction with chest lead ST segment descent was large significantly (P<0.01), and there was no significant differences for chest lead ST segment descent between patients suffering from inferior wall and right ventricle acute myocardial infarction(P>0.05). ②Percent of occurring serious ventricular arrhythmia and auricular-ventricular block in patients with chest lead ST segment descent was large significantly (P<0.05). Conclusion Inferior wall acute myocardial with chest lead ST segment descent indicate that harm of heart cell is extensive and the possibility of occurring serious ventricular arrhythmia and auricular-ventricular block is improved.
