Effect and Safety of Flecainide and Metoprolol Versus Metoprolol Alone to Suppress Ventricular Arrhythmias in Arrhythmic Mitral Valve Prolapse

Flecainide is mainly used for pharmacological conversion in patients with atrial tachyarrhythmias and to suppress ventricular arrhythmias in patients with structurally normal hearts.

Metoprolol is a beta-blocker and class II antiarrhythmic drug considered standard care in most cardiac diseases predisposing to ventricular arrhythmias, including arrhythmic mitral valve prolapse.
