本文作者回顾性研究150例经心电图证实的心房纤颤(以下简称房颤)患者的病历,结果表明房颤最常见原因为高血压病或同时伴缺血性心脏病。31％患者发生过血栓性栓塞症,其中大多数发作累及脑循环。发生血栓性栓塞症最危险的时间是在房颤刚开始时。栓塞症的复发是常见的,复发最危险时期是在首次发作后的头二周内。由于房颤引起的栓塞性梗塞比血栓性梗塞范围大,故有半数以上患者会立即死亡或在一年内死亡,或者严重丧失 The authors retrospectively reviewed the medical records of 150 patients with atrial fibrillation confirmed by electrocardiogram (ECG). The results showed that the most common cause of atrial fibrillation was hypertension or ischemic heart disease. Thromboembolism occurred in 31% of patients, most of which involved the cerebral circulation. Thrombotic embolism occurs the most dangerous time is in the beginning of atrial fibrillation. Recurrence of embolism is common, with the most dangerous period of recurrence occurring within the first two weeks after the first episode. Because of the large range of embolic infarcts caused by AF compared with thrombotic infarctions, more than half of these patients die immediately or die within a year or are severely lost
