Assessment of P Wave Peak Time and P Wave Dispersion in Patients with COVID-19 Infection.

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_max), and PWPT. Results: It was determined that the P_max and PD values of the patients infected with the COVID-19 virus were higher than the control group (p<0.001). PWPT_D2 (p<0.001), PWPT_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_max, PD, PWPT_D2 and PWPT_V1. There was the same correlation relationship between WBC with P_max, PD, PWPT_D2 and PWPT_V1. Conclusion: Significant prolongation of PWPT and PD in COVID-19 patients may be predictive in determining the risk of developing atrial fibrillation. [ABSTRACT FROM AUTHOR]
