心房扑动(atrialflutter,AF;下简称房扑)是一种较为常见的房性心律失常,临床上根据心电图检查分为典型房扑和非典型房扑,根据心内电生理检查可分为峡部依赖性房扑与非峡部依赖性房扑。频率规整而房室传导比例固定的峡部依赖性房扑很容易通过普通体表心电图确立诊断。对于体表心
Atrial flutter (AF; hereinafter referred to as atrial flutter) is a more common atrial arrhythmia, clinically based on the ECG is divided into typical atrial flutter and atypical atrial flutter, according to electrophysiological examination can be divided into isthmus Dependent atrial flutter and non-isthmus-dependent atrial flutter. Frequency is regular and atrioventricular conduction rate isobaric fixed isthmus atrial flutter is easily established by the general surface ECG diagnosis. For the body surface heart
