[Effect of the sympathetic nervous system in regulating heart rhythm during burst stimulation of the vagus nerve].
In cat experiments, the right inferior cardiac nerve was stimulated at a frequency of 2 and 4 Hz and the right vagus by bursts of 1, 2, 4, 8 and 16 impulses. Stimulation of the inferior cardiac nerve shifted the ranges of the heart rate control up the frequency scale. The shift of the range boundaries was mainly determined by the intensity of sympathetic regulation and by the number of impulses in a burst which stimulates the vagus nerve.
