Patent ID: 8649862

Claim:
A system, comprising: a medical device, comprising: a processor circuit; a therapy circuit configured to provide a specified defibrillation therapy to a tissue site, the specified defibrillation therapy including a scheduled completion, the therapy circuit including a protection circuit configured to adjust specification of the specified defibrillation therapy being provided so as to provide an adjusted defibrillation therapy before the scheduled completion; and a monitoring circuit comprising a comparator, the monitoring circuit configured to monitor a therapy circuit defibrillation therapy output energy parameter using the comparator during providing the specified defibrillation therapy; wherein the comparator is configured to compare the therapy circuit defibrillation therapy output energy parameter with a specified threshold corresponding to a fault; and wherein the monitoring circuit is configured to trigger the protection circuit to adjust specification of the specified defibrillation therapy when the therapy circuit defibrillation therapy output energy parameter exceeds the specified threshold as indicated by the comparator; wherein the monitoring circuit and the protection circuit are configured to operate asynchronously with respect to the processor circuit and without requiring the intervention of the processor circuit.
