Abstract

The role of the right and left stellate ganglion (RSG, LSG) in the cardiac response to exercise was determined in 34 chronically instrumented dogs. The dogs were divided into three groups: control, left stellectomized (LSGx), and right stellectomized (RSGx). Heart rate (HR), left circumflex coronary flow velocity (CF), and left ventricular pressure were measured during a graded submaximal exercise program on a motor-driven treadmill. At the greatest work load, 6.4 kph and 16% grade, HR in the control group was 235 ± 5 beats/min, after LSGx was 258 ± 6 beats/min (P
