Abstract
A system includes an implantable electrical stimulation lead configured for intravenous introduction into a vessel proximate to a heart and an electrical stimulator. The lead comprises a lead body and at least three electrode segments. The electrical stimulator is coupled to the electrode segments and configures a first of the electrode segments as a first anode, a second of the electrode segments as a cathode, and a third of the electrode segments as a second anode, and delivers electrical stimulation to the heart via the cathode and first and second anodes. Additional techniques for delivering electrical stimulation include using multiple electrode segments as cathodes and electrically isolating other electrode segments. Other examples are directed to techniques for directing electrical therapy to a vagus nerve of a patient.
