本文分析了AMI并发Af的可能原因及其治疗,发现多部位梗塞、心功能降低和高龄可能与发生Af有关。若Af发生后,心功能障碍伴心室率过快,用小剂量西地兰和氨酰心安治疗效果较好;若仅出现快速心室率,而心衰不明显,可单用氨酰心安。 This article analyzes the possibility of AMI complicated with Af and its treatment, found that multi-site infarction, decreased cardiac function and elderly may be related to the occurrence of Af. If Af occurs, heart dysfunction with ventricular rate too fast, with a small dose of cedilanid and atenolol treatment is better; if only rapid ventricular rate, and heart failure is not obvious, can be used alone atenolol.
