Diastolic pressure and peripheral resistance during stellate ganglion stimulation

Abstract

The mechanism of the diastolic pressure elevation occurring during left stellate ganglion stimulation was investigated. The cardiac output rose considerably, the heart rate remained essentially unchanged, and the total peripheral resistance fell moderately. The diastolic rise appeared to be due to increased blood flow rather than to any active changes in resistance vessels.

“…Freis et al (66) suggest that this typical elevation of diastolic pressure is caused pri marily by an increase in stroke volume as they observed that, although the cardiac output increased with stellate ganglion stimulation, heart rate was essentially unchanged and there was a modest fall in total peripheral resist ance.…”
