Claim:
1. 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 whether or not the patient has had an epileptic seizure; receiving a cardiac signal of the patient; analyzing the cardiac signal to determine the patient's heart rate; determining whether said epileptic seizure 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 said determination, wherein said determination is that the patient has not had an epileptic seizure, wherein the epileptic seizure is characterized by a decrease in the patient's heart rate, wherein the first electrical signal is not a vagus nerve conduction blocking electrical signal; and applying a second electrical signal to a vagus nerve of the patient, based on said determination, wherein said determination is that the patient has had an epileptic seizure, wherein the epileptic seizure is characterized by a decrease in the patient's heart rate, wherein the second electrical signal is a pulsed electrical signal that blocks action potential conduction in the vagus nerve.
