Patent ID: 8781582

Claim:
A device for delivering vagal stimulation comprising: monitoring apparatus configured to monitor physiological parameters of a patient, wherein the monitoring apparatus comprises at least one electrode to monitor the electrical activity of the patient's heart; a sensing module 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 to deliver ventricular arrhythmia therapy to patient's heart; and a control module 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 after the delivery of electrical stimulation to the patient's vagus nerve, adjust the electrical stimulation delivered to the patient's vagus nerve based on the analysis of the monitored physiological parameters, terminate the delivery of electrical stimulation to the patient's vagus nerve after exhausting adjustments to the electrical stimulation delivered to the patient's vagus nerve, and initiate delivery of ventricular arrhythmia therapy to the patient's heart following the termination of the delivery of electrical stimulation to the patient's vagus nerve after the exhaustion of adjustments.
