早在1963年,Schamroth和Marriott首先提出隐匿性室性期前收缩(concealedventricular extrasystoles)这个概念,此后国内外文献陆续有类似报道,随着动态心电图的发展,并将有更多病例发现。本文拟就隐匿性室性期前收缩的心电图表现加以综合,以冀提高对隐匿性室性期前收缩的认识和判断水平。一、隐匿性室性期前收缩二联律当长时间心电图记录时,有时可观察到室性早搏呈特殊分布规律,即显性室性早搏(manifest ventrieular extrasystole)之间的窦性心动数目总是呈奇数。这种奇异现象可用持续性室性早搏二联律解释。如图1所示。a为显性室性早搏,它与几乎同步下传的窦性搏动2在房室连接处发生干扰,使2不能下传。按照一般早搏二联律规律,
As early as 1963, Schamroth and Marriott first proposed the concept of concealed ventricular contraction (concealed ventricular extrasystoles). Since then, domestic and foreign literatures have been reported in succession. With the development of Holter, more cases will be discovered. This article intends to integrate latent ventricular systolic ECG performance in order to improve the occult premorbid contractions awareness and judgment. First, the occult ventricular premature contraction Bigeminal law When the long-term ECG records, sometimes can be observed premature ventricular contractions were in a special distribution, that is, between the ventricular extractive ventricular manifestations of ventricular extractions Is odd. This strange phenomenon can be explained by persistent ventricular premature beats. As shown in Figure 1. a is dominant premature ventricular contractions, it with almost simultaneous sinus beats 2 in the AV junction interference, so that 2 can not be downloaded. In accordance with the law of general premature beats,
