Variability in heart rate recovery measurements over 1 year in healthy, middle-aged adults. [PDF]

open access: yes, 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.

Determinants of short-period heart rate variability in the general population [PDF]

open access: yes, 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 ...

Dual Attention Network for Heart Rate and Respiratory Rate Estimation

open access: yes2021 IEEE 23rd International Workshop on Multimedia Signal Processing (MMSP), 2021
Heart rate and respiratory rate measurement is a vital step for diagnosing many diseases. Non-contact camera based physiological measurement is more accessible and convenient in Telehealth nowadays than contact instruments such as fingertip oximeters since non-contact methods reduce risk of infection. However, remote physiological signal measurement is

Identification of heart rate-associated loci and their effects on cardiac conduction and rhythm disorders [PDF]

open access: yes, 2011
Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we identified 14 new loci associated with heart rate and ...
