Electrodes are capable of delivering synchronized cardioversion and pacing energy pulses as well as defibrillation energy pulses to a patient. The electrodes are also appropriate for use with an automatic or semi-automatic external defibrillator (AED) as well as defibrillators capable of cardioversion and manual defibrillators. The electrodes have a plurality of conductors sized for delivering electrotherapy to patients of different sizes. Preferably, conductors can be used singly or in combination for therapy. The electrodes may also be separated to form electrodes of smaller dimension for application to a smaller patient.
