1. A treatment method, comprising:
applying an electrical current to a vagus nerve of a subject suffering from atrial fibrillation (AF); and
repeatedly changing at least one parameter of the current, so as to restore normal sinus rhythm (NSR) of the subject,
wherein applying the current comprises:
applying a stimulating current and an inhibiting current;
configuring the stimulating current to induce action potentials in a first set and a second set of nerve fibers of the vagus
nerve; and
configuring the inhibiting current to inhibit the induced action potentials traveling in the second set of nerve fibers, the
nerve fibers in the second set having generally larger diameters than the nerve fibers in the first set.
