Patent Images
1. A method of terminating a cardiac arrhythmia in a patient comprising delivering an electrical stimulus between a first implanted electrode disposed on a canister implanted in the patient and at least one of second and third implanted electrodes also implanted in the patient wherein:
- the canister houses circuitry for generating and controlling delivery of the electrical stimulus;
each of the first, second and third implanted electrodes is disposed at a subcutaneous location over the patient'"'"'s ribcage;
the second implanted electrode is disposed in a substantially vertical position over the patient'"'"'s heart, adjacent the sternum;
the third implanted electrode is disposed in a substantially vertical position left of the second implanted electrode; and
the canister is disposed superior to the second and third implanted electrodes.
