Abstract excerpt
Power spectral analysis of heart rate variability (HRV) provides quantitative phenotypic markers of autonomic nervous system activity. Reported determinants of HRV only partially explain its variability in the population. The purpose of this study was to estimate the contribution of genetic factors to the variance in HRV measures and assess the heritability of HRV. Subjects who underwent Holter recordings at a...
