The classic pattern of the typical WP's consists of (1) progressive lengthening of the P-R intervals with the largest increment occuring in the second conducted beat, (2) progressive decrease in P-R increment which accounts for the progressive shortening of successive R-R intervals, and (3) the pause produced by the nonconducted P-wave is less than two P-P intervals. In 45 patients with atrial pacing-induced Wendkebach periods of A-V conduction, the structure of these was studied with His bundle recordings. Of the 128 periods analyzed exceeding 3:2 A-V conduction ratios, 66 per cent were atypical. In 24 patients with spontaneous WP's of A-V conduction, the electrocardiographic records were studied. Of the 98 periods analyzed exceeding 3:2 A-V conduction ratios, 86 per cent were atypical. WP's with A-V conduction ratios greater than 6:5 were all atypical. Five categories of atypical WP's are described.
典型文氏现象（WP）的经典模式包括：（1）P-R间期进行性延长，最大增量出现在第二个下传搏动中；（2）P-R增量进行性减小，这导致连续的R-R间期逐渐缩短；（3）未下传P波产生的长间歇小于两个P-P间期。在45例心房起搏诱发的房室传导文氏周期患者中，通过希氏束记录对其结构进行了研究。在分析的超过3:2房室传导比例的128个周期中，66%为非典型。在24例房室传导自发性WP患者中，对心电图记录进行了研究。在分析的超过3:2房室传导比例的98个周期中，86%为非典型。房室传导比例大于6:5的WP均为非典型。描述了五类非典型WP。
