AIMS 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 metoprolol from electrocardiogram data, and to support our findings with simulated data(More)
The purpose of the present study is to evaluate the effect of rate control drugs on the AV node characteristics during atrial fibrillation (AF) using a model-based approach. A statistical model of the AV nodal function is employed, defined by parameters which characterize the arrival rate of atrial impulses, the refractoriness of the fast and the slow(More)
BACKGROUND High-sensitivity troponin I (hs-TnI) and troponin T (hs-TnT) are moderately correlated and independently related to outcome in atrial fibrillation (AF). Rate controlling therapy has been shown to reduce hs-TnT, however the potential impact on hs-TnI levels, and whether this differs from the effects on hs-TnT, has not been investigated previously.(More)
The aim of the present study was to evaluate the effect of rate-control drugs on variability and irregularity of RR series in patients with AF. We analyzed data of 30 patients (age 72 ± 8 years, 23 men) with permanent AF, from the RATAF (RATe control in Atrial Fibrillation) study. Three 20-min segments were selected at baseline, during beta-blocker(More)
