Flecainide is a potent and orally active antiarrhythmic agent. Flecainide blocks the cardiac fast inward Na+ current (INa) and the rapid component of the delayed rectifier K+ current. Flecainide prolongs the action potential duration (APD) in ventricular and atrial muscle fibres. Flecainide has the potential for the research of fetal tachycardias.
