DownloadFall 2021
Introduction: Pregnancy is associated with profound changes to the sympathetic nervous system control of blood pressure while maintaining blood pressure itself. This involves a coordinated increased muscle sympathetic nerve activity (MSNA) alongside reduced sympathetic baroreflex gain (BRG) and...
