Noninvasive Assessment of Atrioventricular Nodal Function: Effect of Rate‐Control Drugs during Atrial Fibrillation

During atrial fibrillation (AF), conventional electrophysiological techniques for assessment of refractory period or conduction velocity of the atrioventricular (AV) node cannot be used. We aimed at evaluating changes in AV nodal properties during administration of tecadenoson and esmolol using a novel ECG‐based method.
