Seizure detection based on work level excursion
First Claim
1. A medical device, comprising:
- a body data module configured to receive body data from a patient;
a work level data module configured to determine a first work level for the patient during a first time period, and a second work level for the patient during a second time period;
a work level excursion module configured to;
determine whether the second work level exceeds the first work level by an amount greater than a first work level excursion threshold which indicates that the second work level has a current body signal value which is incommensurate to an expected body signal value range for the second work level; and
detect a work level excursion based upon the determination that the current body signal value for the second work level is incommensurate to the expected body signal value range for the second work level which indicates an epileptic seizure event; and
a controller configured to perform at least one of generating a warning of the epileptic seizure event, providing a therapy for the epileptic seizure event, or logging an occurrence of the epileptic seizure event, in response to detecting the work level excursion.

Abstract
We report a method of determining an occurrence of an epileptic convulsive seizure in a patient, comprising: receiving body data from a patient during a first time period, determining a work level relating to said first time period at least based partially upon said body data; determining whether said work level exceeds an extreme work level threshold; performing a responsive action, in response to a determination that said work level exceeds said extreme work level threshold. We also report a medical device system configured to implement the method. We also report a non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform the method.

18. A medical device, comprising:
-
a body data module configured to receive body data from a patient; a work level data module configured to determine a first patient work level during a first time period and a second patient work level during a second time period; a work level excursion module configured to; determine whether the second work level exceeds the first work level by an amount greater than a first work level excursion threshold which indicates a first state; and determine a change in body data from the first work level to the second work level; and a controller configured to perform at least one of generating a warning, providing a therapy, or logging data related to the first state when the change in the body data is not commensurate with the second work level, the controller further configured to suppress the warning and the therapy when the change in the body data is commensurate with the second work level, the controller further configured to log data relating to at least one of the first work level, the second work level, and the change in the body data when the change in the body data is commensurate with the second work level. - View Dependent Claims (19, 20)

21. A medical device, comprising:
-
a body data module configured to receive body data from a patient; a work level data module configured to determine a first work level for the patient during a first time period and a second work level for the patient during a second time period; a work level excursion module configured to; determine whether the second work level does not exceed the first work level by an amount greater than a first work level excursion threshold; determine if the body signal value correlated with the second work level not exceeding the first work level by the amount greater than the first work level excursion threshold is incommensurate with the second work level; and when the body signal value is incommensurate with the second work level not exceeding the first work level by the amount greater than the first work level excursion threshold which indicates an epileptic seizure event, perform via a controller at least one of generating a warning of the epileptic seizure event, providing a therapy for the epileptic seizure event, or logging an occurrence of the epileptic seizure event.

22. A medical device, comprising:
-
a body data module configured to receive body data from a patient; a work level data module configured to determine a first work level for the patient during a first time period and a second work level for the patient during a second time period; a work level excursion module configured to; determine whether the second work level does not exceed the first work level by an amount greater than a first work level excursion threshold which is associated with a first body signal value; determine if a change in the first body signal value associated with the second work level is outside of a range; and determine an epileptic seizure when a determination that the change in the first body signal value is outside of the range and occurred during the second time period; and a controller configured to perform at least one of generating a warning of the epileptic seizure, providing a therapy for the epileptic seizure, or logging an occurrence of the epileptic seizure.
