我院近年来先后遇到“心房分离“心电图二例,均描记自老年慢性肺心病、心力衰竭患者。二例心电图的共同特征是:窦性心律,偶发或频发房早P’,同时可见频率分别为46次/分和33-42次/分的小P’波,P”与P、P’或QRS可见重叠,但互不干扰。近来不少作者强调在诊断心房分离时应排除各种可能的伪差,尤其应该排除呼吸肌肌电伪差,否则就不尽可靠。方炳森又提出将屏气试验作为常规的鉴别手段。但不少重危病人不一定能顺利进行此项试验。此时,
In recent years, our hospital has met two cases of “atrial septation” electrocardiogram, both described from old chronic pulmonary heart disease, heart failure patients. Two common characteristics of ECG are: sinus rhythm, sporadic or frequent room early P ’, while the frequency was 46 times / min and 33-42 times / min small P’ wave, P "and P, P ’ Or QRS visible overlap, but do not interfere with each other.Recently, many authors emphasize that in the diagnosis of atrial septum should be excluded from a variety of possible pseudo-poor, in particular, should rule out the respiratory muscle EMG, otherwise it is not reliable.Fang Bingsen also proposed to hold the breath Test as a routine means of identification, but many critically ill patients may not be able to successfully carry out the test at this time,
