Introduction: One of the unique challenges for obstetricians in pregnancy is cardiovascular changes. This study aimed to evaluate electrocardiographic (ECG) changes in mothers with COVID-19. Materials and Methods: In a retrospective study, 89 pregnant women with positive reverse transcription-polymerase chain reaction for COVID-19, between 19 and 44 years old, were selected for the study, and 12 lead ECGs were extracted and recorded from the medical documents for all cases and all parameters analyzed. Results: Of the 89 patients that met inclusion criteria, only eight patients were admitted to intensive care unit. Of all, 64 cases (71.9%) had normal ECG, three patients showed atrioventricular (AV) block (3.4%), and three patients had first-degree AV block type (PR interval >200 ms). The mean QTC interval was 428.6 ± 37.4 ms and 15 (17%) patients had long QTC intervals (QTC ≥460 ms). There was a significant relationship between antivirus treatment (P = 0.027), as well as hydroxychloroquine (HCQ) with PR interval (P = 0.002). A significant relationship was found between corticosteroids with QTC (P = 0.019) and antibiotics with QTC (P = 0.018). Conclusion: A significant association between corticosteroids usage and QTC interval as well as antiviral and HCQ treatment with PR interval. These changes during pregnancy and COVID-19 should be interpreted with caution by physicians. Understanding changes in electrocardiography can help in better and early diagnosis and management of pregnant mothers to prevent adverse outcomes.
