Abstract
Disclosed are methods and systems for treating epilepsy by stimulating a main trunk of a vagus nerve, or a left vagus nerve, when the patient has had no seizure or a seizure that is not characterized by cardiac changes such as an increase in heart rate, and stimulating a cardiac branch of a vagus nerve, or a right vagus nerve, when the patient has had a seizure characterized by cardiac changes such as a heart rate increase.
Claims13
A method of treating a patient having epilepsy comprising:
- receiving at least one body data stream;
- analyzing the at least one body data stream using a seizure detection algorithm to detect a first condition where an epileptic seizure event has occurred and a second condition where the epileptic seizure event is not present;
- receiving a cardiac signal of the patient;
- analyzing the cardiac signal to determine the patient's heart rate;
- based on a first determination that the first condition is present, determining whether the epileptic seizure event is characterized by a decrease in the patient's heart rate from a reference value or a normative value;
- applying a first electrical signal to a vagus nerve of the patient based on the first determination that the first condition is present and that the epileptic seizure event is characterized by the decrease in the patient's heart rate from the reference value or the normative value;
- and
- applying a second electrical signal to the vagus nerve of the patient based on a second determination that the second condition is present.
