临床上急性心肌梗塞(AMI)患者约有20%合井房颤,房颤多发生在心肌梗塞(MI)24小时后,通常由心包炎或心衰引起。但AMI后最初几小时发生房颤较罕见,对其病因也缺乏了解。本文同的是探索AMI最初几小时发生房颤的病因. 作者观察214例AMI患者(男性167例,女性47例。平均年龄59±11岁。下壁心肌梗塞120例,前壁心肌梗塞94例)中,7例(3%)在胸痛3小时内发生房颤。7例均为左冠状动脉回旋支左房分支近端闭塞出现下壁心肌梗塞,其中5例为急性左房分支闭塞,其余2例是在以往有左回旋动脉闭塞
Approximately 20% of patients with acute myocardial infarction (AMI) in the clinic have atrial fibrillation. Atrial fibrillation usually occurs 24 hours after myocardial infarction (MI) and is usually caused by pericarditis or heart failure. However, the first few hours after AMI occur atrial fibrillation is rare, but its lack of understanding of the cause. This article is to explore the first few hours of AMI with AF cause of etiology. The authors observed 214 patients with AMI (167 males and 47 females, mean age 59 ± 11 years, 120 cases of inferior myocardial infarction, 94 cases of anterior myocardial infarction ), 7 (3%) developed AF within 3 hours of chest pain. 7 cases were left coronary artery left circumflex artery occlusion of the left atrial occlusion of the inferior wall myocardial infarction, of which 5 cases of acute left atrial branch occlusion, and the remaining 2 cases in the past with left circumflex artery occlusion
