[Effect of burst stimulation of the vagus nerve on the excitability of the atria of the cat].
In acute experiments, synchronization of cardiac and vagal rhythms was achieved during burst stimulation of a vagus nerve. The study of atrial excitability in the synchronization revealed changes of diastolic threshold, effective and total refractory periods, the changes being unrelated to the synchronization phenomenon and due to variation of the heart rate.
