Objective: This study aims to evaluate P wave distribution (PD) and P wave peak time (PWPT) in COVID-19 patients. Materials and Methods: A total of 140 participants were recruited in our study. The COVID-19 group included 74 subjects, and the control group included 66 individuals. Between the two groups, PD was compared for electrocardiographic P-wave measurements, including abnormal P wave axis, P wave terminal force in V1 (PWTF), P wave max duration ([P.sub.max]), and PWPT. Results: It was determined that the [P.sub.max] and PD values of the patients infected with the COVID-19 virus were higher than the control group (p<0.001). [PWPT.sub.D2] (p<0.001), [PWPT.sib.V1] (p<0.001) and abnormal P wave axis ratio (p<0.05) were found to be significantly longer in COVID-19 patients. Serum CRP and WBC values were found to be significantly higher in COVID-19 patients (p<0.001, p<0.001, respectively). Also, a significant and positive correlation was detected between CRP and [P.sub.max], PD, [PWPT.sub.D2] and [PWPT.sub.V1]. There was the same correlation relationship between WBC with [P.sub.max], PD, [PWPT.sub.D2] and [PWPT.sub.V1]. Conclusion: Significant prolongation of PWPT and PD in COVID-19 patients may be predictive in determining the risk of developing atrial fibrillation.
