A non-invasive technique for recording the Cardiac activity of the tropical-subtropical mangrove Oyster Crassostrea brasiliana
(2015-01-01)
In this study, we searched the electric signal of the heart of Crassostrea brasiliana; the cardiac activity of 7 individuals was monitored and recorded for a week. The heart beat rates were clearly detected and showed low ...
Maternal, fetal and neonatal heart rate and heart rate variability in Holstein cattle
(2019-01-01)
The aim of this study was to describe the normal values for maternal, fetal and neonatal heart rate (HR) and heart rate variability (HRV) indexes in the time domain (standard deviation of beat-to-beat interval- SDNN; root ...
Relationship between resting heart rate and anthropometric, metabolic and hemodynamic parameters in the elderly aged 80 years and over
(Universidade Estadual Paulista, 2016)
This study examined the relationship between resting heart rate (RHRr) and anthropometric, metabolic and hemodynamic parameters in subjects aged 80 years and over. One hundred thirteen individuals were divided into two ...
Relationship between resting heart rate and anthropometric, metabolic and hemodynamic parameters in the elderly aged 80 years and over
(2016-01-01)
This study examined the relationship between resting heart rate (RHRr) and anthropometric, metabolic and hemodynamic parameters in subjects aged 80 years and over. One hundred thirteen individuals were divided into two ...
Comparison of Polar(®) RS800G3(™) heart rate monitor with Polar(®) S810i(™) and electrocardiogram to obtain the series of RR intervals and analysis of heart rate variability at rest
(Wiley-Blackwell, 2014)
The Polar(®) RS800G3(™) rate monitor was released in the market to replace the Polar(®) S810i(™) , and few studies have assessed that the RR series obtained by this equipment is reliable for analysis of heart rate variability ...
Impacto da desnutrição na modulação autonômica cardíaca em crianças
(2016-11-01)
Objective To compare the autonomic behavior between malnourished children and a control group using analysis of heart rate variability (HRV). Method Data were analyzed from 70 children who were divided into two groups: ...
Autonomic control of heart rate exhibits diurnal shifts in a crocodilian
(2008-10-01)
Over the diurnal cycle most reptiles show large changes in internal body temperature and heart rate (fH). The raising of fH, as the surface of a heliothermic reptile warms, increases cardiac output and facilitates in ...
The autonomic control and functional significance of the changes in heart rate associated with air breathing in the jeju, Hoplerythrinus unitaeniatus
(Company of Biologists Ltd, 2007-12-01)
The jeju is a teleost fish with bimodal respiration that utilizes a modified swim bladder as an air-breathing organ (ABO). Like all air-breathing fish studied to date, jeju exhibit pronounced changes in heart rate (f(H)) ...
