P Wave Dispersion in COVID-19

Abstract

The effects of COVID-19 on the heart are still not fully known. In this study, we investigated how COVID-19 affects the P interval. Electrocardiographies (ECG) of 30 COVID-19 patients and the control group consisting of 23 healthy volunteers were examined and dispersion (Pd) of the P wave was calculated. Compared to control group mean Pd (40,1±6,6 vs. 49,6±11,5, p=0,006) values were significantly higher in Covid19 patients. Increased Pd was observed as an indication that COVID-19 affects the atriums.
