A comprehensive accuracy assessment of Samsung smartwatch heart rate and heart rate variability.

PLoS ONE, 2022
BackgroundPhotoplethysmography (PPG) is a low-cost and easy-to-implement method to measure vital signs, including heart rate (HR) and pulse rate variability (PRV) which widely used as a substitute of heart rate variability (HRV).

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.

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

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 ...
