Figure 2 Interactions Among Vagosympathetic Trunks, ARGP, IRGP, and SLGP on SAN and AVN Function
(A) Modulation of sinus rate by vagosympathetic stimulation. (B) Modulation of ventricular rate during atrial fibrillation by vagosympathetic stimulation. Thick lines and thin lines indicate strong and weak regulatory effects, respectively. See text for details. AVN = atrioventricular node; LVG = left vagosympathetic trunk; RVG = right vagosympathetic trunk; SAN = sinoatrial node; other abbreviations as in Figure 1.
