[Control of cardiac rhythm by stimulation of the vagus nerve in bursts in the rat].
Burst stimulation of the vagus nerve in rats made it possible to obtain the ranges of the heart rate regulation. The increase of the number of impulses in a burst from 1 to 16 leads to a consistent decrease in the range of regulation from respectively 72.1 and 66.7% to 30.4 and 25% of the initial rate. The maximal range (10.1% of the initial rate) is reached with 4 impulses in a burst. The phenomenon of the regulation is reversed by atropine.
