ABSTRACT:
A method and device for treating an electrical problem in an organ, especially a heart, of a human or animal patient comprises atraumatically blocking the transmission of one or more electrical signals external to the organ. Nerve cell membranes near a cathode are depolarized while nerve cell membranes near an anode are hyperpolarized, inducing a DC conduction block. The method and device are especially suitable for treating atrial tachycardia where unwanted signals from at least one pulmonary vein and/or at least one fat pad are blocked within the construct of the heart.
