Heart Rate Variability Complexity in the Aging Process

Electrocardiographic Analysis of Heart Rate Variability in Aging Heart

تغییرپذیری ضربان قلب Heart rate variability))

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...

Heart rate variability and exercise in aging women.

BACKGROUND Our group has shown a positive dose-response in maximal cardiorespiratory exercise capacity (VO(2max)) and heart rate variability (HRV) to 6 months of exercise training but no improvement in VO(2max) for women ≥60 years. Here, we examine the HRV response to exercise training in postmenopausal women younger and older than 60 years. METHODS We examined 365 sedentary, overweight, hype...

Does the Aging Process Significantly Modify the Mean Heart Rate?

BACKGROUND The Mean Heart Rate (MHR) tends to decrease with age. When adjusted for gender and diseases, the magnitude of this effect is unclear. OBJECTIVES To analyze the MHR in a stratified sample of active and functionally independent individuals. METHODS A total of 1,172 patients aged > 40 years underwent Holter monitoring and were stratified by age group: 1 = 40-49, 2 = 50-59, 3 = 60-69...
