Intermittent bigeminal and trigeminal ventricular premature beats were recorded in an otherwise healthy 14 year old male. Coupling intervals progressively lengthened until an ectopic beat was dropped. Odd numbers of sinus beats occurred between bigeminal runs. This rhythm is interpreted as being due to Wenckebach-type block in an exit pathway from the ectopic focus, resulting in concealment of the persistently active extrasystolic mechanism.
在一名14岁健康男性中记录到间歇性二联律和三联律室性早搏。联律间期逐渐延长，直至一个异位搏动脱落。二联律发作之间出现奇数个窦性搏动。这种节律被解释为由于异位起搏点传出途径的文氏型阻滞，导致持续活跃的早搏机制被隐匿。
