Addition of 24‐Hour Heart Rate Variability Parameters to the Cardiovascular Health Study Stroke Risk Score and Prediction of Incident Stroke: The Cardiovascular Health Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundHeart rate variability (HRV) characterizes cardiac autonomic functioning. The association of HRV with stroke is uncertain. We examined whether 24‐hour HRV added predictive value to the Cardiovascular Health Study clinical stroke risk score (CHS‐

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.

Effect of Somatic Experiencing Resiliency-Based Trauma Treatment Training on Quality of Life and Psychological Health as Potential Markers of Resilience in Treating Professionals

Frontiers in Neuroscience, 2018
Background: Individuals who treat trauma are at significant risk of vicarious traumatization and burnout. Somatic Experiencing® (SE®) is a resiliency-focused trauma treatment modality designed to address autonomic nervous system (ANS) dysregulation and ...

Heart rate and respiratory rate influence on heart rate variability repeatability: effects of the correction for the prevailing heart rate

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.

Does resting heart rate measured by the physician reflect the patient’s true resting heart rate? White-coat heart rate

Indian Heart Journal, 2018
Objectives: In cardiology, resting heart rate (HR) and blood pressure (BP) are key elements and are used to adapt treatment. However HR measured in consultation may not reflect true resting HR.

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

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
