Dynamic monitoring heart rate and blood pressure of patients hospitalized with COVID-19. During hospitalization, heart rate and blood pressure were recorded every day at the same time by nurses. The dynamic monitoring results of heart rate (a), systolic blood pressure (b), and diastolic blood pressure (c) were compared between non-severe and severe cases. d The counts of normal blood pressure, preexisting hypertension, and new onset hypertension cases in non-severe and severe groups. e Rate of preexisting hypertension, new onset hypertension, and the total hypertension were compared between non-severe and severe subgroups. *P < 0.05, **P < 0.01, ***P < 0.001 for Non-severe vs Severe
