Claim 10:
11. A method comprising:
implanting a pulse generator (PG) within a lateral region of a chest of a patient, the PG having a housing that includes a PG electrode; and
implanting at least one lead having first and second electrodes that are coupled to be electrically common with one another, wherein the first and second electrodes are elongated and are interconnected by an intermediate segment joined to a distal end of the first electrode and a proximal end of the second electrode, the implanting comprising:
positioning the first electrode subcutaneously proximate to a lower end of a sternum of the patient,
positioned the second electrode subcutaneously along a first parasternal region proximate to the sternum of the patient, the second electrode located at a position, relative to a midline of the sternum, that is vertically below the first electrode;
orienting the first electrode to extend in a non-parallel direction relative to a direction of the second electrode;

configuring the electronics module to provide electrical shocks for antiarrhythmic therapy along a shocking vector extending between the first and second electrodes and the PG; and
wherein at least one of the first and second electrodes has an active length that is 7-11 cm to define an impedance along the shock vector between the first and second electrodes and the PG to be no more than 64 ohms.
