Heart rate and respiratory rate influence on heart rate variability repeatability: effects of the correction for the prevailing heart rate [PDF]
Frontiers in Physiology, 2016 Background: Since heart rate variability (HRV) is associated with average heart rate (HR) and respiratory rate (RespRate), alterations in these parameters may impose changes in HRV.

Anatomy of the Heart with the Highest Heart Rate [PDF]
Journal of Anatomy, 2021 ABSTRACTShrews occupy the lower extreme of the seven orders of magnitude mammals range in size. Their hearts are large relative to body weight and heart rate can exceed a thousand beats a minute. To investigate whether cardiac traits that are typical mammalian scale to these extremes, we assessed the heart of three species of shrew (genusSorex ...

Circadian rhythm of heart rate and heart rate variability [PDF]
Archives of Disease in Childhood, 2000 Measurements of heart rate variability (HRV) are increasingly used as markers of cardiac autonomic activity.To examine circadian variation in heart rate and HRV in children.A total of 57 healthy infants and children, aged 2 months to 15 years, underwent ambulatory 24 hour Holter recording.

Variability in heart rate recovery measurements over 1 year in healthy, middle-aged adults. [PDF]
, 2014 This study assessed the longer-term (12-month) variability in post-exercise heart rate recovery following a submaximal exercise test. Longitudinal data was analysed for 97 healthy middle-aged adults (74 male, 23 female) from 2 occasions, 12 months apart.

Impact of Heart Rate Fragmentation on the Assessment of Heart Rate Variability
Applied Sciences, 2020 Heart rate fragmentation (HRF) is a type of sinoatrial instability characterized by frequent (often every beat) appearance of inflection in the R-R interval time series, despite the electrocardiograms appearing to be sinus rhythm.

A Methodical Approach to Scrutinize the Role of Body Mass Index in Heart Rate Increment and Recovery
Journal of Gandhara Medical and Dental Sciences, 2022 OBJECTIVES Heart rate (HR) is a crucial health indicator and is also one of the health factors we need to pay explicit attention to. Body Mass Index (BMI) is considered a cofactor in heart-related issues like heart rate increment and recovery. Thus a
