摘要：

Authors' Synopsis: Selective perfusion of the sinus and A-V nodes in dogs and simulation experiments with a system of two interacting relaxation oscillators were used to study the nature of the PR interval. The PR interval duration appears to be composed of a relatively fixed conduction delay, and of a labile portion determined by the local excitability of the A-V node region.
