Do sympathetic and parasympathetic blockades alter the power spectrum of heart rate and blood pressure variability in fetal lambs?
Population
Chronically instrumented fetal lambs
Comparison
Administration of sympathetic and… vs Baseline (before administration of blockades)
Design
Preclinical

These spectral changes in fetal lambs warrant no clinical change; extends frequency-specific autonomic mapping but requires human confirmation.
Do sympathetic and parasympathetic blockades alter the power spectrum of heart rate and blood pressure variability in fetal lambs?
Autonomic activity is directly associated with specific frequency components of heart rate and blood pressure variability spectra in fetal lambs.
Kimura et al. (1996) studied this question.
