Chronobiologic blood pressure assessment: Maturation of the daily rhythm in newborn foals
Circadian rhythmicity of physiological processes in animals has been described for some variables. In order to investigate the daily rhythmicity of blood pressure, seven foals (Equus caballus) were used for 40 days after birth. Measurements of blood pressure were done by means of an oscillometric ap...
