1. A device for providing vagal stimulation comprising:
- monitoring apparatus configured to monitor physiological parameters of a patient, wherein the monitoring apparatus comprises at least one electrode configured to monitor the electrical activity of the patient'"'"'s heart;
a sensing module operably coupled to the monitoring apparatus and configured to receive the monitored physiological parameters;
a therapy delivery module configured to deliver electrical stimulation to the patient'"'"'s vagus nerve; and
a control module operably coupled to the sensing module and to the therapy delivery module and configured to;
detect a supraventricular tachycardia using the monitored physiological parameters,initiate delivery of electrical stimulation to the patient'"'"'s vagus nerve upon detecting the supraventricular tachycardia,analyze the monitored physiological parameters for termination criteria after initiating delivery of electrical stimulation to the patient'"'"'s vagus nerve, wherein analyzing the monitored physiological parameters comprises determining whether the R-R intervals within the electrical activity of the patient'"'"'s heart have increased, andterminate the delivery of electrical stimulation to the patient'"'"'s vagus nerve if the R-R intervals within the electrical activity of the patient'"'"'s heart have not increased.

Abstract
The disclosure herein relates generally to methods for treating heart conditions using vagal stimulation, and further to systems and devices for performing such treatment. Such methods may include monitoring physiological parameters of a patient, detecting cardiac conditions, and delivering vagal stimulation (e.g., electrical stimulation to the vagus nerve or neurons having parasympathetic function) to the patient to treat the detected cardiac conditions.

9. A method of providing vagal stimulation comprising:
-
monitoring physiological parameters of a patient, wherein the physiological parameters comprise the electrical activity of the patient'"'"'s heart; detecting a supraventricular tachycardia using the monitored physiological parameters; initiating delivery of electrical stimulation to the patient'"'"'s vagus nerve upon detecting the supraventricular tachycardia; analyzing the monitored physiological parameters for termination criteria after initiating delivery of electrical stimulation to the patient'"'"'s vagus nerve, wherein analyzing the monitored physiological parameters comprises; determining whether the R-R intervals of the electrical activity of the patient'"'"'s heart have increased, and determining whether the patient'"'"'s cardiac condition is worsening delivering electrical stimulation to the patient'"'"'s vagus nerve; and terminating the delivery of electrical stimulation to the patient'"'"'s vagus nerve if the R-R intervals within the electrical activity of the patient'"'"'s heart have not increased or the patient'"'"'s cardiac condition is worsening. - View Dependent Claims (10, 11, 12, 13, 14, 15)
