Abstract

Background: There have been case reports showing that Covid-19 infection caused arrhythmic cases but the pathogenesis is unclear. The relationship between atrial conduction times, PwD and PwPD with atrial tachyarrhythmias have been demonstrated in some studies. We investigate the effect of different clinical presentations of Covid-19 infection on these parameters ,in this study. Methods: We divided the patients who infected with Covid-19 into three groups according to CT and PCR test results. P-max, P-min, PwD and PwPD were calculated in the ECGs of these patients prior to start of treatment. Results: P-max was significantly higher in Group-1 than in Group-2 and Group-3. P-min was significantly lower in Group-1 than in Group 3. PwD was significantly higher in Group-1 compared to Group-2 and Group-3, and it is significantly higher in Group-2 than Group-3. While PwPD was significantly higher in Group-1 than in Group-2 and Group-3. Conclusion: Patients with pneumonia with PCR positivity seem to have the highest risk of atrial tachyarrhythmia that is why that group may benefit most from strict ECG follow-up.
