Flecainide acetate is a recently introduced, class 1 antiarrhythmic agent that is highly effective in the treatment of ventricular and atrioventricular/ nodal reentrant tuchycardias. 1,2 Although both intravenous and orally administered flecainide are known to cause an increase in the pacing threshold, 3 an abrupt and potentially lethal rise in threshold causing failure of a properly functioning, newly implanted pacing system has not to our knowledge been described. We report such a case to stress the need for caution when using this drug in elderly pacemaker patients.
