Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...
Among rate control strategies for atrial fibrillation is atrioventricular junction ablation with ventricular pacing. Concerns about the long term safety of this procedure emerge as studies report deleterious effects of right ventricular pacing. A cohort of patients having undergone atrioventricular node ablation and right ventricular pacing was retrospectively studied. After 5 years of follow-u...
A 2 1/2-year-old girl with bradycardia and left bundle branch block at birth began to experience "night cries" when deeply asleep. Electrophysiological study demonstrated congenital diffuse atrioventricular conduction disease with concealed paroxysmal atrioventricular block, nonpropagated His bundle depolarizations, severe sinus node abnormality, and a low atrioventricular junctional escape rhy...
