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.
