Influence of Clinical Aspects and Genetic Factors on Feline HCM Severity and Development.

Hypertrophic cardiomyopathy (HCM), which is associated with thickening of the left ventricular wall, is one of the most common heart pathologies in cats. This disease has a hereditary etiology and is primarily related to mutations in the and genes. This study aims to determine the effect of the presence of heterozygosity or homozygosity for the p.

Parameters of Heart Rate Variability in Male Wistar Rats under Conditions of Different Motor Activity.

We studied heart rate variability indexes in freely moving male Wistar rats at rest and under conditions of increased motor activity (treadmill exercise). Some regularities were revealed in the dynamics of HR, RRNN, Mo, indicator of the adequacy of regulation processes, VLF (msec2, %), HF, LF (%), LF/HF, and IC that characterize changes in the neurohumoral regulation and shifts in the level of cardiac rhythm control at the different stages of the experiment. It was found that changes in motor activity of male Wistar rats were accompanied by the transition of the functional state of the organism to a new level of regulation, which was confirmed by the dynamics of HR, RRNN, Mo, LF, VLF, LF/HF, and IC.
