Abstract

A method and system for providing pulsed electrical stimulation to vagus nerve(s) for providing therapy for cardiovascular disorders such as atrial fibrillation, congestive heart failure, inappropriate sinus tachycardia, and refractory hypertension. Method and system comprising implantable and external components. Power source for the stimulation pulses may be external or implantable. In the preferred embodiment, the implanted stimulator can function as a stimulus-receiver for use with an external stimulator, or may function as a programmable implanted pulse generator (IPG). The external stimulator having capability for networking with other computers, whereby the programs of external stimulator may be remotely controlled over a wide area network. The programmer also having means for networking to exchange data with remote computers.
