Variability of the rhythm of isolated rat heart.
Variability of the rhythm of Langendorff-perfused isolated rat heart was compared to that of human and rat hearts in vivo. The rate and variability of the rhythm of isolated rat heart differed from those in vivo. It was shown that intracardiac mechanisms regulating heart activity affect the main parameters of heart rate variability.
