A system and method for stimulating a human heart including a sensing
module coupled through a lead to an electrode associated with a tissue of
the human heart for sensing electrical activity of the heart. A
controller module may be coupled to the sensing module. The controller
module may select between a temporary stimulation therapy and a chronic
stimulation therapy. Also included is a therapy module coupled to the
controller, the therapy module communicating a plurality of anodic pulses
to the heart through the lead when providing the temporary stimulation
therapy. The amplitude, frequency, and duration of the anodic pulses may
be varied, and biphasic pacing may also be used. The electrode may be a
drug-eluting electrode for delivery of a drug. After an event occurs, the
controller module may transition to the chronic stimulation therapy that
may include cathodic stimulation.
