1. Instantaneous and averaged heart rate profiles: Developing strategies for programming pacing rates in dogs

Author:

Subject:
heart rate,   etc   ; arrhythmia; dogs;     Show all 3 Subjects
Abstract:
... Pacemakers use heart rate histograms (% beats) and sensor indicated rate histograms (% time) to illustrate rate distributions. When programmed to the rate adaptive modes, these data are used to determine the appropriateness of rate response to activity. These histograms are generated from instantaneous heart rate calculations. In humans, such data are compared to known histographic rate profiles. ...

Abstract:
... Heart rate is one of the gold standards used to assess the workload level and fitness of horses. However, when slight differences need to be detected, it is not sensitive enough. Therefore, the aim of this study was to test the effect of competition level and phase of exercise on the heart rate and heart rate variability parameters in show jumpers. Fourteen horses were examined competing on three ...

Abstract:
... The fields that develop methods for sensory substitution and sensory augmentation have aimed to control external goals using signals from the central nervous systems (CNS). Less frequent however, are protocols that update external signals self-generated by interactive bodies in motion. There is a paucity of methods that combine the body-heart-brain biorhythms of one moving agent to steer those of ...

Abstract:
... Personality describes the average behaviour and responses of individuals across situations; but personality traits are often poor predictors of behaviour in specific situations. This is known as the “personality paradox”.We evaluated the interrelations between various trait and state variables in participants’ everyday lives. As state measures, we used 1) experience sampling methodology (ESM/EMA) ...

Abstract:
... August Krogh pioneered a view of cardiac output that emphasised the rate of venous return, and stressed the importance of changing the filling of the ‘inadequately’ supplied heart, instead of changes in heart rate or cardiac inotropy. Krogh, by and large, presented this concept in three manuscripts published in 1912, which relied on innovative experimental techniques (developed in collaboration wi ...

Arterial stiffness is a predictor of cardiovascular events and can be assessed through augmentation index (AIx) and pulse wave velocity (PWV). This study was intended to analyse the arterial stiffness in three categories, hypertensive pregnant women vs. healt ...
