detection circuitry;

energy delivery circuitry capable of delivering a plurality of cardiac therapies comprising at least a tachycardia therapy, a bradycardia therapy, and an asystole prevention therapy;

therapy instructions stored in the energy delivery circuitry, the therapy instructions executable to direct delivery of the plurality of cardiac therapies;

one or more electrodes configured for subcutaneous, non-intrathoracic placement in a patient and for coupling to the detection circuitry and energy delivery circuitry;

detection circuitry configured to receive cardiac signals using the one or more electrodes and detect a tachycardia condition, a bradycardia condition, and an asystole condition using the cardiac signals;

a controller coupled to the detection circuitry and energy delivery circuitry, the controller, in response to a cardiac condition requiring treatment, executing at least some of the therapy instructions to coordinate delivery of a selected one of the tachycardia, bradycardia, and asystole prevention therapies, the asystole prevention therapy being delivered at a rate below that of the bradycardia therapy and at 20 pulses per minute or less upon detection of the asystole condition;

a patient-external communications device configured to receive data relating to the selected one of the tachycardia, bradycardia, and asystole prevention therapies, wherein the patient-external communications device facilitates communication with a network or server system; and

a display coupled to the patient-external communications device for displaying the received data.
