Background: SARS-CoV-2 is increasingly recognized for its cardiovascular complications. To address the knowledge gap in our region, this study investigated the relationship between electrocardiographic (ECG) features and in-hospital mortality among COVID-19 patients.
Methods: A prospective cohort study was conducted involving 140 RT-PCR-confirmed COVID-19 patients at Dhaka Medical College Hospital from August 2021 to July 2022. Patients were divided into two groups based on ECG findings: normal (Group A) and abnormal (Group B). Clinical data and ECG parameters were analyzed using SPSS 24.0.
Results: Patients with abnormal ECGs were older, more likely male, and presented with higher rates of dyspnea and palpitations. They were also at increased risk of severe COVID-19 and had longer hospital stays. In-hospital mortality was significantly higher in Group B (21.4% vs.4.3%). ST-T changes and atrial fibrillation were associated with increased mortality. Independent predictors of in-hospital mortality included ECG abnormalities and admission SpO₂ < 90%.
Conclusion: ECG abnormalities are significantly associated with adverse outcomes in COVID-19 patients. Further large-scale studies are warranted to strengthen these findings.
