Key result
Endocardial transcatheter 50 Hz AV node stimulation reduced the ventricular rate to below 85 bpm after 4 days in a patient with acute heart failure and chronic atrial fibrillation.
Why the study?
Does 50 Hz AV node stimulation improve hemodynamics and control ventricular rate in a patient with acute heart failure and chronic AF with rapid ventricular response?

Does 50 Hz AV node stimulation improve hemodynamics and control ventricular rate in a patient with acute heart failure and chronic AF with rapid ventricular response?
Endocardial transcatheter stimulation of the AV nodal fat pad may be a viable strategy to control rapid ventricular response in patients with AF and acute heart failure undergoing pacemaker implantation.
Bianchi et al. (2008) conducted a case report in Acute heart failure and chronic atrial fibrillation (n=1). AV node stimulation via posteroseptal atrial lead was evaluated on Ventricular rate. Endocardial transcatheter 50 Hz AV node stimulation reduced the ventricular rate to below 85 bpm after 4 days in a patient with acute heart failure and chronic atrial fibrillation.
