ABSTRACT:
A cardiac pacing apparatus and method. A cardiac pacing apparatus (24) provides a cardiac pacing signal to a plurality of electrode pairs (20, 22), each comprising a positive electrode (20a, 22a) and a negative electrode (20b, 22b). A plurality of isolated current sources (30, 32) supply the electrode pairs with separate electric pacing currents, each small enough in magnitude so as to avoid patient discomfort or burning. The plurality of pacing currents delivered to the electrode pairs add to produce a total cardiac pacing current of sufficient magnitude to cause contraction of a heart muscle through which the pacing currents flow.
