No: A pacemaker will only keep the heart rate at above a certain level if your intrinsic heart rate drops to that level. A defibrillator will shock the heart similar to an external shock from a paramedic or er doc in a situation of cardiac arrest or sudden cardiac death. This is most lilely the situation you are referring to.
