  • Method and apparatus using vagal stimulation for control of ventricular rate during atrial fibrillation
    Patent number: 5916239
    Abstract: A closed-loop, variable-frequency, vagal-stimulation apparatus for control of ventricular rate during atrial fibrillation. In one embodiment the apparatus includes a stimulator applied to the left vagus nerve and a controller programmed to automatically and continuously adjust the vagal stimulation frequency as a function of the difference between actual and desired ventricular excitation rates. In a second embodiment the apparatus includes a vagal nerve stimulator and a controller which automatically adjusts the vagal stimulation frequency as a function of the difference between ventricular excitation rate and arterial pulse rate in order to eliminate or minimize pulse deficit.
    Type: Grant
    Filed: November 24, 1997
    Date of Patent: June 29, 1999
    Assignee: Purdue Research Foundation
    Inventors: Leslie A. Geddes, Tarek Elabbady, William E. Schoenlein, Matthew Waninger, Joe D. Bourland
  • Method and apparatus using vagal stimulation for control of ventricular rate during atrial fibrillation
    Patent number: 5690681
    Abstract: A closed-loop variable frequency vagal stimulation apparatus for control of ventricular rate during atrial fibrillation. In one embodiment the apparatus includes a stimulator applied to the left vagus nerve and a proportional controller programmed to automatically and continuously adjust the vagal stimulation frequency proportionally as a function of the difference between actual and desired ventricular excitation rates. In a second embodiment the apparatus includes a vagal nerve stimulator and a controller which automatically adjusts the vagal stimulation frequency as a function of the difference between ventricular excitation rate and arterial pulse rate in order to eliminate or minimize pulse deficit.
