Key result
Young African Americans manifested a pattern of heart rate variability response similar to older Caucasian Americans, suggesting signs of premature autonomic nervous system aging.
Why the study?
Do age and ethnicity affect short-term heart rate variability in adults?
Population
135 subjects (57 African Americans and 78 Caucasian Americans), aged 23 to 54 years

Do age and ethnicity affect short-term heart rate variability in adults?
Young African Americans exhibit heart rate variability patterns similar to older Caucasian Americans, suggesting premature autonomic nervous system aging that may contribute to hypertension risk.
Choi et al. (2006) reported a cross-sectional. Age and ethnicity was evaluated on Heart rate variability indices (HF, LF power, and LF/HF). Young African Americans manifested a pattern of heart rate variability response similar to older Caucasian Americans, suggesting signs of premature autonomic nervous system aging.
