Preventing use of vagal stimulation parameters

摘要

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.

主权项

1. A device for delivery of 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 a control module coupled to the sensing module and to the therapy delivery module and configured to:
analyze the monitored physiological parameters after 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,determine whether the patient's cardiac condition is worsening after the delivery of electrical stimulation to the patient's vagus nerve,terminate the delivery of electrical stimulation to the patient's vagus nerve if the patient's cardiac condition is worsening,store the parameters of the electrical stimulation delivered to the patient's vagus nerve associated with the worsening of the patient's cardiac condition, anddeliver, at a later time following termination of the delivery of electrical stimulation to the patient's vagus nerve, electrical stimulation to the patient's vagus nerve at one or more stimulation parameters, wherein the control module is configured to prevent, at the later time following termination of the delivery of electrical stimulation, delivery of the electrical stimulation to the patient's vagus nerve at the previously stored parameters associated with the worsening of the patient's cardiac condition.
