  • Values represent mean ± SD % change in parameters from prestimulation value (n = 6). PreCSD represents hemodynamic values immediately before removal of the stellate ganglia. PostCSD values represent hemodynamic parameters after a 30-min period of stabilization after removal of stellate ganglia. HR, heart rate; bpm, beats per minute; dP/dtmax, dP/dtmin, maximum and minimum dP/dt; LVESP, left ventricular end-systolic pressure; BL, baseline; BSGS, bilateral stellate ganglion stimulation; BMCGS, bilateral middle cervical ganglion stimulation.

  • * P value < 0.05 for % change from baseline (prestimulation).

  • P = 0.08 for % increase in LVESP with BMCGS PreCSD vs. PostCSD.

  • § P = 0.02 for comparison of % change in LVESP for BSGS vs. BMCGS.
