The combined effects of parasympathetic and sympathetic stimulation on right atrial contractile strength were assessed in open-chest, pentobarbital-anesthesized dogs. A factorial experimental design was employed to quantify the percent changes in atrial contractile strength in spontaneously beating and paced hearts as a function of the frequencies of vagal and stellate ganglion stimulation. In 7 of 10 dogs, there was a substantial interaction between the two autonomic divisions; the… CONTINUE READING
