Dynamic Modelling of Heart Rate Response Under Different Exercise Intensity
Heart rate is one of the major indications of human cardiovascular response to exercises. This study investigates human heart rate response dynamics to moderate exercise. A healthy male subject has been asked to walk on a motorised treadmill under a predefined exercise protocol. ECG, body movements, and oxygen saturation (SpO2) have been reliably monitored and recorded by using non-invasive por...
متن کاملChanges in heart rate and heart rate variability as a function of age in Thoroughbred horses
We investigated changes in heart rate (HR) and HR variability as a function of age in newborn foals to old Thoroughbred horses. Experiments were performed on a total of 83 healthy and clinically normal Thoroughbred horses. Resting HR decreased with age from birth. The relationship between age and HR fit the equation Y=48.2X-0.129(R2=0.705); the relationship between age and HR for horses 0-7 yea...
متن کاملIntrinsic heart rate response as a predictor of rate-adaptive pacing benefit.
OBJECTIVE More than half of the pacemaker systems now being implanted can be rate adaptively paced. Our objective was to determine which patients benefit from rate-adaptive pacing in terms of improvement in maximum performance and aerobic capacity. METHODS Thirty patients with implanted accelerometer-driven, rate-adaptive pacemakers underwent a standardized, ergospirometrically and maximally ...
متن کاملPerception of speech rate as a function of vocal intensity and frequency.
The study was designed to examine the possibility that vocal frequency and vocal intensity influence the perception of sppech rate. One 30-second segment of spontaneous speech was used to produce nine stimulus segments that factorially varied three levels of vocal frequency and three levels of vocal intensity but were identical in speech rate. The segments were recorded backwards in pairs such ...
متن کاملHeart rate variability and heart rate recovery as prognostic factors
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...
