Does not change clinical practice; leaves open chick embryo utility for modeling developmental cardiovascular control.
Observational (n=7)
The avian embryo model demonstrates complex, repeatable patterns of heart rate fluctuation during development, suggesting its utility for studying cardiovascular control systems.
Moriya et al. (2000) conducted an observational in Developmental physiology (chick embryos) (n=7). Continuous measurement of instantaneous heart rate was evaluated on Instantaneous heart rate (fh) fluctuations. Continuous monitoring of 7 chick embryos revealed complex, repeatable patterns of instantaneous heart rate fluctuations that change during development from prenatal day 18 to post-hatch day 2.
