1. An implantable medical device (IMD), comprising:
a pulse generator (PG) configured to be positioned within a lateral region of a chest of a patient, the PG having a housing that includes a PG electrode, the PG having an electronics module; and
an elongated lead that is electrically coupled to the pulse generator, the elongated lead including a first electrode that is configured to be positioned along a first parasternal region proximate a sternum of the patient and a second electrode that is configured to be positioned at an anterior region of the patient, wherein the first and second electrodes are coupled to be electrically common with one another, wherein the electronics module is configured to provide electrical shocks for antiarrhythmic therapy along at least one shocking vector between the PG electrode and the first and second electrodes, wherein the anterior region is located proximate to a lower end of the sternum, the second electrode configured to be oriented to extend in a non-parallel direction relative to a direction of the first electrode, the second electrode located at a position, relative to a midline of the sternum, that is vertically below the first electrode, the first electrode having a length that is greater than a length of the second electrode.
