Abstract:
A method of implementing tripolar cardiac stimulation in a heart, comprising the steps of:(a) implanting a cardiac stimulation device having anodic and cathodic connections and including means for providing electrical stimulation pulses through said anodic and cathodic connections; (b) electrically connecting first and second electrode lines to respective ones of the anodic and cathodic connections; (c) electrically coupling at least two electrodes to one of the electrode lines; (d) electrically coupling at least one electrode to the other electrode line; and (e) implanting at least one of the at least two electrodes electrically coupled to the one electrode line and the at least one electrode electrically coupled to the other electrode line in a heart chamber; and (f) implanting at least one other of the at least two electrodes electrically coupled to the one electrode line in a blood vessel of the heart.
