分支型室性心动过速,频率在60—110次/分左右,特征为QRS不增宽或较室上性下传者稍宽,常呈不完全性右束支传导阻滞及左前分支阻滞图形,一般认为属于加速性定性自身节律(AIVR)。但分支型室速亦可呈并行收缩性,我们在心脏监护病房遇到一例,报道如下。患者男性,40岁,因发作性心悸、胸闷二天于1985年1月5日急诊入院。入院前三天有轻度感冒症状。过去有高血压史,但无类似的心悸发作史。体检:T37.3℃,P80次/分,BP 150/104。神志清,平卧位,咽部轻度充血。 Branched ventricular tachycardia, the frequency of 60-110 beats / min or so, characterized by QRS is not widened or slightly wider than the supratentorial, often incomplete right bundle branch block and the left front branch block resistance Hysterical graphics, generally considered to be accelerated qualitative self-rhythm (AIVR).
