Patent ID: 8352027

Claim:
A cardiac rhythm management system comprising: a cardiac resynchronization therapy module for providing cardiac resynchronization therapy in a cardiac resynchronization mode; a pacemaker module for providing bradycardia therapy in a pacemaker mode; sensing circuitry to collect electrophysiological data; a selector module coupled to the cardiac resynchronization therapy module and the pacemaker module, wherein the selector module is configured to select an operating mode from among a plurality of operating modes including the cardiac resynchronization therapy module and the pacemaker module; wherein the selector module is configured to automatically select between the cardiac resynchronization therapy module and the pacemaker module so that a current operating mode is either the cardiac resynchronization mode or the pacemaker mode, wherein the selection is based upon the collected electrophysiological data; a controller programmed to store operating parameters associated with the current operating mode as a reversion mode and, after recovery from a disruption to system operation, retrieve the operating parameters stored as the reversion mode and reset the current operating mode based thereon.
