Patent ID: 8108046

Claim:
A method of treating a nervous system disorder in a patient, the method comprising: sensing a brain signal from the patient; obtaining a neurological event detection signal, the neurological event detection signal indicating neurological events detected from the brain signal; sensing a cardiac signal from the patient; obtaining a cardiac event detection signal, the cardiac event detection signal indicating cardiac events detected from the cardiac signal; analyzing timing relationships between detected events before enabling therapy delivery for treating a neurological disorder in response to a cardiac event, the detected events including detected neurological events and detected cardiac events; identifying a matched event when one of the detected neurological events is temporally related to one of the detected cardiac events; determining that the cardiac event detection signal facilitates detection of neurological events when the timing relationships between detected neurological events and detected cardiac events meet one or more predetermined criteria; and delivering a therapy to the patient for treating the neurological disorder in response to a cardiac event if the cardiac event detection signal is determined to facilitate detection of neurological events.
