- a housing configured for implantation in a patient;
energy delivery circuitry provided in the housing, the energy delivery circuitry configured to deliver only two forms of cardiac therapy, the two forms of cardiac therapy comprising a non-physiologic, life sustaining pacing therapy and a therapy to treat a tachyarrhythmia;
detection circuitry provided in the housing, the detection circuitry configured to detect cardiac rhythms;
a lead system comprising one or more lead electrodes, the lead system coupled to the energy delivery circuitry and the detection circuitry; and
control circuitry provided in the housing and coupled to the energy delivery circuitry and the detection circuitry the control circuitry configured to coordinate delivery of the tachyarrhythmia therapy in response to detection of a tachyarrhythmia requiring treatment and delivery of the non-physiologic, life sustaining pacing therapy in response to detection of cardiac asystole.

Abstract
Preventing sudden cardiac death involves providing an implantable device configured to deliver only two forms of cardiac therapy, the two forms of cardiac therapy including an anti-tachyarrhythmia therapy and an asystole prevention pacing therapy. The tachyarrhythmia therapy is delivered in response to detecting a tachyarrhythmia, and the pacing therapy is delivered in response to detection of cardiac asystole. An implantable cardiac device for preventing sudden cardiac death may be configured to be fully operational upon setting a therapy On/Off parameter and two or less programmable parameters associated with therapy delivery. Control circuitry configures the device for operation to prevent sudden cardiac death after programming the two or less programmable parameters and enabling the therapy On/Off parameter.
