Methods for inducing fibrillation utilizing subcutaneous electrodes
First Claim
1. A method of inducing fibrillation in a patient, the method comprising providing a shock to the patient using an implanted first electrode on a lead secured to an implanted canister, the shock being provided between the first electrode and an electrode provided on the implanted canister, wherein the shock is delivered from non-vascular and non-cardiac locations.

14. A method of treating a patient susceptible to abnormal cardiac function, the method comprising:
-
providing an implantable stimulus device in a patient, the implantable stimulus device including a power source and an energy storage system; providing a lead system for the stimulus device; implanting the lead system into the patient such tat the lead system does not contact the hearth; sensing a portion of the patient'"'"'s cardiac rhythm; coupling the power source to the energy storage system to charge the energy storage system; and discharging the energy storage system using the lead system to induce fibrillation in the patient'"'"'s heart;
wherein the implantable stimulus device includes a first electrode disposed thereon, and the lead system includes a second electrode, wherein the step of discharging the energy storage system include discharging energy between the first electrode and the second electrode. - View Dependent Claims (15, 16)
