急性前壁心肌梗塞时有些病人会出现下壁导联ST段压低,其病理生理机制和临床意义尚不清楚。本文通过研究下壁导联ST段压低与冠状动脉左前降支病变部位及前壁和侧壁导联中ST段偏移之间的关系来评价其意义。 方法 126例急性前壁心梗病人均在入院21天内行冠状动脉造影,显示冠状动脉狭窄的部位和严重程度;入院时做12导联标准
Acute anterior myocardial infarction in some patients will appear under the lead ST-segment depression, the pathophysiology and clinical significance is not yet clear. This article studies the relationship between ST-segment depression of the inferior leads and the lesion site of the left anterior descending coronary artery and the ST-segment shift in the anterior and lateral leads. Methods 126 patients with acute anterior myocardial infarction were admitted to hospital within 21 days of coronary angiography, showing the location and severity of coronary stenosis; admission to do 12-lead standard
