1. An implantable system, comprising:

  • a defibrillator device subcutaneously implantable superficial to a left atrium of a heart wherein the defibrillator device comprises control logic configured to detect for ventricular fibrillation based on sensed cardiac activity;

    a patch device subcutaneously implantable superficial to an apex of the heart, wherein the patch device comprises control logic, wherein the patch device is communicatively coupled with the defibrillator device via a wireless communication linka subcutaneously implantable wire electrically coupling the defibrillation device with the patch device; and

    a sensor configured to sense cardiac activity, the sensor communicatively coupled with the defibrillator device through the wire such that sensed cardiac activity is received by the defibrillator device;

    wherein in response to the defibrillator device detecting ventricular fibrillation in the heart, the defibrillator device administers a defibrillation shock via the patch device.
