Abstract:
Heart rate fragmentation (HRF) is a type of sinoatrial instability characterized by frequent (often every beat) appearance of inflection in R-R interval time series despite that ECG shows sinus rhythm. Because the assessment of vagal function by the analysis of heart rate variability (HRV) depends on the assumption that the high frequency (HF, 0.15-0.4 Hz) component of HRV is mediated solely by the vagus, HRF that is measured as a part of HF component confounds the assessment of vagal function by HRV. In this study, we analyzed HRF in 24-h ECG big data, ALLSTAR, and investigated the changes in HRF occurrence with age and its influence on the assessment of HF component of HRV. We observed that HRF is often observed during childhoods (0-20 yr) and after 80 yr, but its influence on the HF component of HRV monotonously increases with age.
