紊乱性心房律(CAR),又称多源性房性心动过速,是一种独特的房性心律失常,国内尚少报道。一般认为其心电图特征为:1.同一导联上有连续三种或三种以上的不同形态的P 波和多变之P—P、P—R、R—R 间距;2.没有一个稳定的占优势的心房起搏点;3.P—P间有等电位线;4.心房率多数在100～250次/分之间,亦有低于100次/分者。现将1960～1980年间我院所见到的28倒紊乱性心房律的临床与心电图表现分析如下:
Disordered atrial pace (CAR), also known as multi-source atrial tachycardia, is a unique atrial arrhythmia, less reported in China. It is generally believed that the ECG features are: 1. The same lead with three or more consecutive three different forms of P wave and varying P-P, P-R, R-R spacing; 2. None of the stable Atrial pacemaker; 3. P-P between the potential line; 4. Atrial most in 100 to 250 beats / min, there are less than 100 beats / min. The 1960 to 1980 are now seen in our hospital 28 down chaos atrial rhythm clinical and electrocardiographic performance analysis as follows:
