METHOD AND APPARATUS FOR PREVENTING CARDIAC ARRHYTHMIAS WITH ENDOVASCULAR STIMULATION
First Claim
Patent Images
1. An implantable device, comprising:
- a sympathetic stimulation channel for electrically stimulating sympathetic nerves innervating the heart of a patient;
a sensing channel for sensing a physiological variable reflective of autonomic balance;
a controller programmed to detect autonomic imbalance in the patient; and
, wherein the controller is further programmed to cause the delivery of stimulation pulses through the sympathetic stimulation channel when increased parasympathetic activity is detected.

Abstract
Certain cardiac arrhythmias can be prevented by appropriate electrical stimulation of autonomic nerves innervating the heart. An implantable cardiac rhythm management device is configured to deliver such stimulation when an autonomic imbalance is predicted to be present via an endovascular electrode. Autonomic imbalance may be predicted to be present based upon circadian rhythms, detected heart rates, or detected heart rate variability.
