Fault tolerant pacing

摘要

Methods and/or devices may be configured to monitor the performance of pacing therapy and provide fault-tolerant operation to provide therapy in the event of certain failure modes occurring in the pacing delivery circuits, leads, and/or lead/tissue interfaces. Generally, the methods and/or devices may provide fault-detection, fault-recovery and fault-handling to, e.g., handle potential faults.

主权项

1. A fault detection method for use in detecting one or more faults associated with an implantable medical device that require action to be taken for handling of the one or more faults, the method comprising:
delivering pacing therapy to a patient using an implantable medical device; monitoring one or more parameters of the implantable medical device during the delivery of pacing therapy; identifying at least one suspect parameter in the one or more monitored parameters indicative of one or more faults associated with the implantable medical device that require action to be taken for handling of the one or more faults, wherein, to identify at least one suspect parameter in the one or more monitored parameters indicative of one or more faults, the control module is further configured to execute one or more of analyzing clock speed, testing internal pacing circuitry, and testing discrete component leakage; sensing at least one physiological response of the patient during the delivery of pacing therapy in response to identifying the at least one suspect parameter prior to initiating action to handle the one or more indicated faults; and determining whether a fault exists based on the at least one physiological response sensed during delivery of pacing therapy in response to identifying the at least one suspect parameter prior to initiating action to handle the one or more indicated faults.
