1960年Satoh发现一些室早病例,其相邻两个室早之间的窦性心搏数总是奇数,这种现象以后被Schamroth和Marriott命名为隐匿性室早二联律。其实在隐匿性室早二联律,虽然窦性激动在折返径路内被交替地阻滞,但它们已侵入折返征路的大部分,即隐匿性传导,使随后的窦性激动在折返径路内传导延缓,有利于下次早搏的显现。本文分析20例偶尔呈插入型的室早,旨在明确折返径路内存在隐匿性传导,研究插入对后面早搏的影响。方法 20例室早患者,其中男性17例、女性3例,年龄20—58岁(平均39.6岁),均无原发性心脏病,也不用抗心律失常药物。
In 1960, Satoh found some early cases of ventricular sinus, whose sinus beats were always odd before two adjacent rooms. This phenomenon was later named as the occult ventricular dilatation by Schamroth and Marriott. In fact, in the occult room, the early binary association law, although sinus agitation is alternately blocked in the turnaround path, but they have invaded the majority of the reentry approach, the occult conduction, so that subsequent sinus excitations in the turnaround path Delayed conduction is conducive to the next appearance of premature beats. This article analyzes 20 cases of occasional intercalary ventricular early, designed to clear occult pathways within the existence of occult conduction, to study the impact of insertion on the subsequent premature beats. Methods Twenty patients with early ventricular disease, including 17 males and 3 females, aged 20-58 years (mean 39.6 years), had no primary heart disease and no antiarrhythmic drugs.
