Atrioventricular Nodal Conduction and Refractoriness Following Abrupt Changes in Cycle Length

The properties of the atrioventricular (AV) nodal conduction and effective refractory period in man are generally evaluated at a constant basic cycle length (CL) and, in most cases, they demonstrate an inverse relationship to the drive cycle. The response of AV node to abrupt change in CL is less de...
