Abstract
A system and method is disclosed by which an implantable cardiac device may deliver bradycardia therapy in the event of a system fault. A hardware-based safety core provides the logic circuitry for delivering bradycardia therapy in the form of synchronous pacing in the event of a fault which disables operation of the device's primary control circuitry. The safety core pacemaker eliminates common mode failure of the primary control circuits used in the primary pacing system. Failures in the primary controller memory or execution will activate the safety core pacemaker.
