Abstract

Background: Indirect evidences suggest that the If blocker ivabradine may exert an antiarrhythmic effect in ventricular myocardium in heart failure (HF) patients by inhibiting spontaneous depolarisations, but the clinical relevance of this mechanism is not known. Dobutamine (DOB) has been known to increase heart rate and the incidence of cardiac arrhythmias.
