CARDIAC STIMULATOR WITH BACKUP-MODE SELF-RECOVERY

摘要

A cardiac stimulator (10, 30) with a method and apparatus for automatically switching the cardiac stimulator to its normal mode from its backup mode. A fault monitor (52) receives fault signals and determines whether a particular fault warrants activation of the backup mode. If so, a number of attempts to reactivate the normal mode are permitted (178). The normal mode may be reactivated if the stored information is valid (230) and if the circuitry is operational (236, 238).
