Key result
The study aimed to assess differences in baseline heart rate variability values under different conditions in in vivo experiments involving male rats.
Why the study?
Relevant reference values for HRV parameters in rats are lacking in the literature, leading to significant variability in reported control or baseline values across individual studies.
The study aims to evaluate baseline heart rate variability values in male rats to provide better reference points for interpreting experimental changes.
Supplies male rat HRV baselines for experiments; extends reference data but leaves open clinical translation.
The cardiovascular system is primarily controlled by the autonomic nervous system, and any changes in sympathetic or parasympathetic activity also have an impact on myocardial activity. Heart rate variability (HRV) is a readily available metric used to assess heart rate control by the autonomic nervous system. HRV can provide information about neural (parasympathetic, sympathetic, reflex) and humoral (hormones, thermoregulation) control of myocardial activity. Because there are no relevant reference values for HRV parameters in rats in the scientific literature, all experimental results are only interpreted on the basis of changes from currently measured control or baseline HRV values, which are, however, significantly different in individual studies. Considering the significant variability of published HRV data, the present study focused primarily on comparing control or baseline HRV values under different conditions in in vivo experiments involving rats. The aim of the study was therefore to assess whether there are differences in the starting values before the experiment itself.
