Transition in human heart rate variability indices due to spread of the COVID-19: Comparison of young and elderly groups by ALLSTAR big data analysis

Our lives have changed dramatically since the spring of 2020 due to new coronavirus infection COVID-19. And in an environment where we are required coexist with virus for foreseeable future, teleworking work remotely and social distancing maintain intervals between people required. Thorough prevention measures" "ensuring availability healthcare delivery systems" remain critical. Recent studies shown that patients moderate or severe coronary infections reduced pulmonary diffusion function as a sequela. Thus, changes environment, human organism itself, naturally affect heart rate variability indices. To investigate body acceleration young elderly groups, collected data from Allostatic State Mapping by Ambulatory ECG Repository (ALLSTAR) database on 1342 cases (mean age 22 ± 1 year) group 12,000 2019 2021.) 12,994 72 years) older 2021 were extracted ALLSTAR analyzed. Results showed younger decreasing trend activity spread (P<0.01). The no significant difference 2020, but proportion time spent supine position tended increase
