Introduction: Although COVID-19 is primarily a respiratory disease, the incidence of cardiac involvement is also significant among patients. It is important to assess cardiac complications in patients with COVID-19 because studies have shown that cardiac complications in patients are associated with a worse prognosis, including the need for intensive care unit admission, intubation, and higher mortality. Electrocardiogram (ECG) is a suitable tool for assessing cardiac abnormalities and cardiac involvement in COVID-19 patients. The aim of this study was to investigate the association between patients’ ECG results and their prognosis.
Materials and Methods: In this study, 120 medical records were reviewed, including 60 records related to patients with COVID-19 with ECG changes and 60 patients without ECG changes. The outcome of the patients, including ICU admission, death, or discharge, was extracted from their records. In addition, variables including underlying diseases, Spo2, CRP and Cr were compared in the two groups.
Results: The most common ECG abnormalities were tachyarrhythmia and AF with 18.3% and 16.3%, respectively. There was a significant difference between the two groups in terms of age and SPO2 (p < 0.05). No significant relationship was observed between ECG results and patient prognosis (p > 0.05).
Conclusion: Based on the results, ECG findings cannot be used as a criterion for determining the prognosis of patients with COVID-19, although ECG can be used in the early diagnosis of cardiac symptoms in patients. Also, older age and hypoxemia are two important factors in a worse prognosis of the disease, which indicates the need for timely interventions for these patients.
