Abstract
Methods, systems, and apparatus for detecting an epileptic event, for example, a seizure in a patient using a medical device. The determination is performed by providing an autonomic signal indicative of the patient's autonomic activity; providing a neurologic signal indicative of the patient's neurological activity; and detecting an epileptic event based upon the autonomic signal and the neurologic signal.

A method for detecting an epileptic event based upon a patient's cardiac signal and kinetic activity, comprising:
- providing a cardiac signal indicative of the patient's heart activity;
- determining at least one cardiac index from the cardiac signal, wherein said at least one cardiac index is selected from a heart rate and at least one EKG morphology feature;
- providing a kinetic signal indicative of body movement of the patient;
- detecting an epileptic event based on a change in the at least one cardiac index selected from:
- an increase in the patient's heart rate;
- a decrease in the patient's heart rate;
- or
- a change in said at least one EKG morphology feature;
- and
- performing a further action based on said kinetic signal, wherein said further action is selected from
- confirming the detecting of the epileptic event;
- or
- not confirming the detecting of the epileptic event.
A method for detecting an epileptic event based upon a patient's cardiac signal and kinetic activity, comprising:
- providing a kinetic signal indicative of body movement of the patient;
- determining at least one kinetic index from said kinetic signal, wherein said at least one kinetic index is selected from a body posture, a body position, a fall, a parameter derived from an accelerometer signal selected from a movement, a frequency per unit time, a time interval between movements, a movement direction in at least one plane, an acceleration, a velocity, a force, or a change in one or more of the foregoing;
- providing a cardiac signal indicative of the patient's heart activity;
- detecting an epileptic event based on said at least one kinetic index;
- and
- performing a further action based on said cardiac signal, wherein said further action is selected from
- confirming the detecting of the epileptic event;
- or
- not confirming the detecting of the epileptic event.
A method for detecting an epileptic event based upon a patient's cardiac signal and kinetic activity, comprising:
- providing a cardiac signal indicative of the patient's heart activity;
- determining at least one cardiac index from the cardiac signal, wherein said at least one cardiac index is selected from a heart rate, an EKG morphology feature, an EKG rhythm feature, or an EKG wave interval feature;
- characterizing the at least one cardiac index as either indicative of an epileptic event or not indicative of an epileptic event;
- providing a kinetic signal indicative of body movement and type of body movement of the patient;
- characterizing the kinetic signal as either indicative of an epileptic event or not indicative of an epileptic event;
- and
- detecting an epileptic event only if both of the heart rate and the kinetic signal are indicative of an epileptic event.
A medical device system for detecting an epileptic event based upon multimodal signals, comprising:
- a first sensor for detecting a first modal data and a second sensor for detecting a second modal data relating to a patient's body, the first modal data comprising a kinetic signal and the second modal data comprising a cardiac signal of the patient's body;
- and
- a medical device (MD) coupled to the patient's body and operatively coupled to the first sensor and the second sensor;
- the MD comprising:
- a kinetic signal module for receiving the kinetic signal;
- a cardiac signal module for receiving the cardiac signal;
- a detection module for determining whether an epileptic event has occurred based on:
- 1) detecting an epileptic event using one of said kinetic signal module and said cardiac signal module, and
- 2) confirming or not confirming said epileptic event using the other of said kinetic signal module and said cardiac signal module,
