混乱性房性心动过速(Chaotic atrial tachycardia)也称多源性房性心动过速(multifocal atrial tachycardia)混乱性房性心动过速(缩写 C、A、T,下同)有其特殊的心电图表现与其临床、治疗上的特点。现简略介绍如下:一、心电图表现C、A、T、的临床诊断困难,听诊极似房颤,故 C、A、T、的诊断必须依靠心电图检查。C、A、T、的心电图诊断必须同时具备下列数点见下图。 Chaotic atrial tachycardia also known as multifocal atrial tachycardia (atrial tachycardia) atrial tachycardia (abbreviation C, A, T, the same below) has its own special ECG Performance and clinical, therapeutic characteristics. Now briefly introduced as follows: First, the performance of ECG C, A, T, clinical diagnosis difficult, auscultative atrial fibrillation, so C, A, T, the diagnosis must rely on ECG. C, A, T, ECG diagnosis must also have the following points, see below.
