1. A medical device system comprising:
- a brain monitoring element for sensing activity of the brain and outputting a brain signal based upon the sensed activity of the brain;
a cardiac monitoring element for sensing activity of the heart and outputting a cardiac signal based upon the sensed activity of the heart;
a cardiac therapy module for providing therapeutic output to the heart; and
a processor in communication with the brain monitoring element, the cardiac monitoring element and the cardiac therapy module, the processor configured to;
receive the cardiac signal and detect a cardiac event in the cardiac signal;
activate the cardiac therapy module to provide the therapeutic output to the heart based on the detected cardiac event;
determine if the detected cardiac event is categorized as a neurologically matched cardiac event, a neurologically matched cardiac event comprising a cardiac event occurring within a specified time period of one or more neurological events; and
communicate to the cardiac therapy module to modulate the therapeutic output to the heart if the detected cardiac event is categorized as a neurologically matched cardiac event.

Abstract
A system for regulating or modulating cardiac therapy using brain state information. The modulation may include suppressing standard, prescribed cardiac therapy for a period of time or it may involve modulating the type of cardiac therapy delivered In another embodiment, a system is provided for determining whether a cardiac event is categorized as neurologically matched, and, if so, modulating the therapeutic output to the heart.
