Age and Sex Differences in Heart Rate Variability and Vagal Specific Patterns - Baependi Heart Study.

ABSTRACT:

Background

Heart rate variability (HRV) is a noninvasive method for assessing autonomic function. Age, sex, and chronic conditions influence HRV.

Objectives

Our aim was to evaluate HRV measures exploring differences by age, sex, and race in a sample from a rural area.

Methods

Analytical sample (n = 1,287) included participants from the 2010 to 2016 evaluation period of the Baependi Heart Study, a family-based cohort in Brazil. Participants underwent 24-hour Holter-ECG (Holter) monitoring. To derive population reference values, we restricted our analysis to a 'healthy' subset (i.e. absence of medical comorbidities). A confirmatory analysis was conducted with a subgroup sample that also had HRV derived from a resting ECG 10'-protocol obtained during the same time period
