We also assessed the differences between the patients with and without any significant arrhythmia in Holter monitoring (defined as PVC or PAC burden > 200/d or AF or nsVT), but there were no differences regarding COVID-19 severity (CRP of 78 vs. 133, p = 0.34; WBC of 8.3 vs. 10.6, p = 0.09; CT (% lungs) of 46 vs. 52%, p = 0.92). This evidence concerns the gene CRP and Arrhythmia.
