Dynamics of blood pressure, pulse wave transit time and systolic time intervals during acute gravity changes induced by parabolic flight

Pierre-Francois Migeotte et al. J Gravit Physiol. 2002 Jul.

Abstract

To investigate cardiovascular adaptation to transient microgravity (microgravity), we measured RR intervals (RRI), arterial blood pressure (BP), pulse wave transit time (PTT) and systolic time intervals (STI) during parabolic flight. Our results demonstrate that during microgram RRI, BP and PTT are subject to a rapid adaptation likely mediated by the baroreflex whereas STI changes with microgravity but does not present further adaptation.
