Prevalence of arrhythmia in COVID-19 patients with mild/moderate and severe illness: a prospective cohort study.

Objectives: The type of arrhythmias, and their prevalence in mild/moderate and severe COVID-19 patients admitted to the hospital are unknown from a prospective cohort study.

Methods: We did continuous electrocardiograms along with multiple ECGs in 305 consecutive hospitalized COVID-19 patients.

Results: The incidence of arrhythmias was 6.

A Generalized Measure of Cumulative Residual Entropy.

In this work, we introduce a generalized measure of cumulative residual entropy and study its properties. We show that several existing measures of entropy, such as cumulative residual entropy, weighted cumulative residual entropy and cumulative residual Tsallis entropy, are all special cases of this generalized cumulative residual entropy. We also propose a measure of generalized cumulative entropy, which includes cumulative entropy, weighted cumulative entropy and cumulative Tsallis entropy as special cases.
