Stress and Heart Rate Variability: A Meta-Analysis and Review of the Literature
Psychiatry Investigation, 2018 Objective Physical or mental imbalance caused by harmful stimuli can induce stress to maintain homeostasis. During chronic stress, the sympathetic nervous system is hyperactivated, causing physical, psychological, and behavioral abnormalities. At present,

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.

Interaction between heart rate variability and heart rate in pediatric population.
Frontiers in Physiology, 2015 Background: Heart rate variability (HRV) is primarily heart rate (HR) dependent, and therefore, different HR may exert different impact on HRV. The objectives of the study were to evaluate the effect of HR on HRV in children and to determine whether HRV ...

Correlation of heart rate recovery and heart rate variability with atrial fibrillation progression
Journal of International Medical Research, 2021 Objective To examine the combination of heart rate recovery (HRR) and heart rate variability (HRV) in predicting atrial fibrillation (AF) progression. Methods Data from patients with a first detected episode of AF who underwent treadmill exercise testing

Age-predicted maximal heart rate revisited.
Journal of the American College of Cardiology, 2001 OBJECTIVES We sought to determine a generalized equation for predicting maximal heart rate (HRmax) in healthy adults. BACKGROUND The age-predicted HRmax equation (i.e., 220 - age) is commonly used as a basis for prescribing exercise programs, as a ...

Determinants of short-period heart rate variability in the general population [PDF]
, 2001 Decreased heart rate variability (HRV) is associated with a worse prognosis in a variety of diseases and disorders. We evaluated the determinants of short-period HRV in a random sample of 149 middle-aged men and 137 women from the general population ...

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
