混乱性房性心律文献中曾以《混乱或多源性房性心动过速》、《多源性房性节律紊乱》、《混乱性房性机制》的名称记载。此种心律失常依心房率快慢分为两型:心房率100—200次/分的混乱性房性心动过速和心房率少于100次/分的混乱性房性机制。混乱性房性心律只能以心电图诊断,物理检查常误诊为心房纤颤。其心电图诊断标准:在同一个导联中有3个或更多个不同 Confusion atrial rhythm literature has been “chaotic or multi-source atrial tachycardia”, “multi-source atrial rhythm disorders”, “chaotic atrial mechanism,” the name recorded. Arrhythmia according to the rate of atrial septal divided into two types: atrial rate of 100-200 beats / min of atrial tachycardia and atrial rate of less than 100 beats / min chaotic atrial mechanism. Confusion atrial rhythm can only ECG diagnosis, physical examination often misdiagnosed as atrial fibrillation. Its ECG diagnostic criteria: There are 3 or more differences in the same lead
