Short term blood pressure regulation
SpletOpen-loop gain of the short-term systemic pressure regulation was determined under closed-loop conditions in the closed chest anesthetized dog (n = 5). For this purpose, cardiac output and mean systemic pressure were varied by ventricular pacing after the production of complete heart block. From the … SpletShort-term regulation of the blood pressure includes those regulators that work very fast, from minutes to seconds. There are also long-term regulators but these take days to …
