Influence of age, gender, body mass index, and functional capacity on heart rate variability in a cohort of subjects without heart disease.
We studied the time- and frequency-domain indexes of heart rate variability (HRV) in 653 patients without any evidence of heart disease relative to age, gender, heart rate, body mass index, andExpand

Lower heart rate variability is associated with higher serum high-sensitivity C-reactive protein concentration in healthy individuals aged 46 years or more.
BACKGROUND To test the hypothesis of an association between cardiac autonomic activity evaluated by heart rate variability and systemic inflammatory markers such as C-reactive protein, we studied theExpand
