The purpose of this study is to describe the developmental course of arterial baroreflex
control of heart rate in swine. Tests of baroreflex function were performed with eight …

Objective Despite extensive knowledge about basic baroreceptor function, there continues
to be controversy as to whether there is postnatal maturation of the cardiovascular …

The baroreflex was observed in neonatal swine as young as 4 h of age. Bolus injections of
Na nitroprusside (NP) and phenylephrine (PE), induced changes in blood pressure and …

1. Baroreflex activity was assessed in nine fetal, four new‐born and six adult sheep, using
the relationship between heart period and arterial pressure. Arterial pressure was raised …

Baroreflex activity was assessed in 10 fetal lambs at 85-145 days of gestation. ECG leads
sewn to the fetal chest wall, vinyl catheters in brachial artery and femoral vein, and a balloon …

The purpose of this study was to characterize the developmental changes in baroreflex
function during fetal and postnatal life in sheep. Resting mean arterial blood pressure …

The heart rate (HR) response to stepwise changes in mean arterial pressure (MAP)
produced by methoxamine and sodium nitroprusside was studied in conscious horses, pigs …

To determine if alterations in arterial pressure influenced fetal heart rate variability (HRV),
experiments were carried out in chronically catheterized fetal sheep aged 128–138 d …

The arterial baroreflex is a fundamental reflex that buffers rapid changes in arterial blood
pressure (BP) via regulation of the heart rate and sympathetic nerve activity to the …

The role of the arterial baroreceptors in regulating the fetal circulation was studied in 18
chronically instrumented fetal lambs, 120-136 days gestation. The results were compared to …
