2 Claims

1. A method of providing an electrical cardiac stimulus device to a patient, the method comprising:

cutaneously sensing electric cardiac signals from a patient at a plurality of cutaneous locations using cutaneous electrodes;

identifying cutaneous locations providing improved signal detection;

using the cutaneous locations providing improved signal detection to estimate the best location of the electrical cardiac stimulus device; and

implanting a cardiac stimulus device at the identified best location;

wherein the cardiac stimulus device includes a canister having an electrode thereon and a lead assembly, and the step of implanting the cardiac stimulus device includes placing the lead assembly at only subcutaneous locations, without contacting the heart and without disposing a lead within a blood vessel in or adjacent to the heart.
