This paper presents the evaluation of mental stress assessment using heart rate variability. The activity of the autonomic nervous system (ANS) is studied by means of frequency analysis of the Electrocardiogram (ECG) signal. Spectral decomposition of the Heart Rate Variability before smoking and after smoking was obtained. Mental stress is accompanied by dynamic changes in ANS activity. ECG sig...

Processing of Heart Rate Variability (HRV) signal becomes more and more important for functional assessment of patient’s health. When developing Hybrid Models of cardiopulmonary system we need to make possible taking into account heart rate variability. Our aim is to generate signals that have properties similar to HRV in norm and in different pathologies. Hybrid models of cardiopulmonary syste...

The adoption of fitness tracker devices to monitor training in the equine market is full expansion. However, validity most these has not been assessed. aim this study was examine heart rate (HR) and variability (HRV) measurements during high-intensity exercise by an integrated with electrocardiogram (ECG) (Equimetre) comparison ECG device (Televet). Twenty Thoroughbred racehorses were equipped ...
