title: Application of the Rosenblueth hypothesis to assess atrioventricular nodal behavior.
abstract: Based on the Rosenblueth hypothesis, atrioventricular nodal behavior is evaluated using a method involving the coupling interval at the level of the atrioventricular nodal step delay. If the sum of the coupling interval at the level of step delay and the resultant step delay is greater than the atrial coupling interval, Wenckebach periodicity results; if the sum is less than the atrial coupling interval, the reverse Wenckebach phenomenon occurs; and if both are equal, steady state conduction is reached.
