ECG-based beat-to-beat assessment of AV node conduction properties during AF

ECG-based beat-to-beat assessment of AV node conduction properties during AF

IntroductionThe refractory period and conduction delay of the atrioventricular (AV) node play a crucial role in regulating the heart rate during atrial fibrillation (AF). Beat-to-beat variations in these properties are known to be induced by the autonomic nervous system (ANS) but have previously not...
