Are the electrophysiological properties of the atrioventricular conduction system reproducible over a 60-minute period in humans?
Electrophysiological properties of the atrioventricular conduction system are generally reproducible within one hour, supporting the validity of these techniques for evaluating cardioactive drugs.
Reddy et al. (1975) reported an observational. Time interval (30 and 60 minutes) vs. Baseline (control period) was evaluated on Electrophysiological properties of the atrioventricular conducting system (A-H interval, H-V interval, refractory periods). Repeat electrophysiological measurements of the atrioventricular conducting system over 30 to 60 minutes showed no significant changes from baseline, confirming reproducibility.
