本文通过对42例急性下壁心肌梗死病人的心电图胸前导联ST段下移及T波极向的改变与冠脉造影前降支的病变情况进行比较,发现ST段下移组中70％有前降支病变,非ST段下移组中52.4％有前降支病变,前者明显高于后者,但P>0.05;T波倒置组中92.3％有前降支病变,T波直立组中51.7％有前降支病变,两者有显著差异,P<0.05。ST段下移伴T波倒置组中90％有前降支病变,ST段下移伴T波直立组中50％有前降支病变,前者明显高于后者,但P>0.05,所以我们认为ST下移和T波倒置与前降支病变有关。
In this paper, 42 cases of acute inferior myocardial infarction patients ECG ST-segment elevation of the chest lead and T-wave polar changes and coronary angiography anterior descending branch of the lesion compared with the ST segment found that 70% There was anterior descending branch disease, non-ST segment down group, 52.4% had anterior descending branch disease, the former was significantly higher than the latter, but P> 0.05; T wave inversion group 92.3% had anterior descending branch disease, T wave erection group 51.7% had anterior descending branch disease, there was a significant difference between the two, P <0.05. ST segment down with T wave inversion group, 90% had anterior descending branch disease, ST segment down with T wave erection group, 50% had anterior descending branch disease, the former was significantly higher than the latter, but P> 0.05, so we ST down and T wave that the inversion and the anterior descending artery lesions related.
