Patent ID: 8485979

Claim:
An implantable device for implantation in a head of a patient, the device comprising: a biocompatible housing adapted to be implanted beneath a patient's scalp; a cardiac monitoring element, the cardiac monitoring element adapted to sense cardiac activity to generate a cardiac signal; a brain monitoring element operatively coupled to the housing, the brain monitoring element adapted to sense brain activity to generate a brain signal; and a processor at least partially housed within the housing, the processor configured to (a) receive the cardiac signal from the cardiac monitoring element, (b) identify one or more cardiac events in the cardiac signal, (c) receive the brain signal from the brain monitoring element, (d) identify one or more neurological events in the brain signal, and (e) indicate a relationship between the neurological events and the cardiac events; wherein the processor is further configured to perform the following: (a) for each of the one or more identified neurological events, determine whether the neurological event is within a specified time period of one of the one or more identified cardiac events; and (b) for each of the one or more identified cardiac events, determine whether the cardiac event is within a specified time period of one of the one or more identified neurological events.
