Background: Numerous pro-inflammatory mediators linked to SARS-CoV-2 infection are crucial in the pathogenesis of cardiac and arrhythmic consequences. Hospitalized COVID-19 patients were found to have cardiac damage, which was linked to an increased risk of in-hospital death. Consequently, it's possible that these people are significantly more susceptible to cardiac arrhythmias. Objectives: The aim of the work was to identify cardiac and arrhythmic complications in patients with COVID‐19 at Shebin Elkom Chest Hospital. Methods: A set of 143 patients with COVID‐19 who were admitted to Shebin Elkom  Chest Hospital, 6 declined consent and 17 did not meet the inclusion criteria, 120 patients were willing to participate in the study and consented for participation, during the period time from March 2021 to March 2022. Thus, 120 patients with COVID‐19 were analysed, 8 patients of them had mild grade, 54 had moderate grade and 58 patients had severe grade. Results: Creatine kinase myocardial band was significantly increased among severe patients than mild and moderate patients. Also, positive troponin was the most common among the studied groups, with a significant difference. Moreover, referred to ICU was most common in severe patients (31.03%) compared moderate patients (5.56%) with significant difference among the studied groups. Conclusions: Acute lung injury is a major complication of COVID-19 and causes severe morbidity and mortality. Nonetheless, growing clinical and epidemiological data indicates that COVID-19 infection is linked to cardiac damage and arrhythmic complications.
