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 ...

BACKGROUND Measurements of heart rate variability (HRV) are increasingly used as markers of cardiac autonomic activity. AIM To examine circadian variation in heart rate and HRV in children. SUBJECTS A total of 57 healthy infants and children, aged 2 months to 15 years, underwent ambulatory 24 hour Holter recording. Monitoring was also performed on five teenagers with diabetes mellitus and s...

BACKGROUND AND AIM Heart rate (HR) can appear static and regular at rest, during exercise or recovery after exercise. However, HR is constantly adjusted due to factors such as breathing, blood pressure control, thermoregulation and the renin-angiotensin system, leading to a more dynamic response that can be quantified using HRV (heart rate variability). HRV is defined as the deviation in time b...
