急性心房梗死由于确诊困难、临床症状易于被心室梗死掩盖以及临床医师对其认识不足而较少受到重视。急性心房梗死常为右房梗死,心电图上P-Ta段的变化及房性心律失常是其特征性的表现。心肌梗死急性期出现的房颤一部分就是由于出现了心房梗死,常发生在右冠脉于窦房结动脉发出前闭塞或回旋支于左心房回旋支发出前闭塞的病例。本文对心房梗死的发生率、临床特征、诊断标准及治疗予以综述,表明心房梗死不同于心室梗死的临床过程及对心肌梗死预后产生影响,以引起临床医师的重视。 Acute atrial infarction due to the diagnosis difficult, clinical symptoms easily covered by ventricular infarction and less understanding of clinicians less attention. Acute atrial infarction is often right atrial infarction, P-Ta segment of the ECG changes and atrial arrhythmia is its characteristic performance. Acute myocardial infarction occurs in part because of atrial fibrillation occurs atrial infarction, often occurs in the right coronary artery in the sino-atrial node before the issue of occlusion or malalignment in the left atrium before the supination occlusion cases. This article reviews the incidence of atrial infarction, clinical features, diagnostic criteria and treatment, which shows that atrial infarction is different from the clinical course of myocardial infarction and prognosis of myocardial infarction in order to arouse the attention of clinicians.
