Electrocardiographic excerpts from three patients demonstrate bigeminy, concealed bigeminy, trigeminy, concealed trigeminy, and Wenckebach's pattern of variation in the coupling interval from sinus beat to ventricular ectopic beat. These diverse manifestations of ventricular ectopy support the hypothesis that reentry in man reflects conduction of an initial impulse, with delay, to cause the coupled reentrant beat.
三名患者的心电图摘录显示了二联律、隐匿性二联律、三联律、隐匿性三联律以及从窦性搏动到室性异位搏动的配对间期的文氏变化模式。室性异位的这些不同表现支持了这样一种假说，即人体中的折返反映了初始冲动的传导，并伴有延迟，从而导致配对的折返搏动。
