Arrhythmia in a COVID-19 patient: A case report

Abstract

In this study, we considered an 83-year-old male patient admitted to the Al-Zahra hospital emergency department in Isfahan. He complained of fatigue, weakness, headache, and cough. In addition, he had hallucinations and delusions for two days; but he had no fever and chill. His physical examination showed a blood pressure of 170/100 mm Hg, heart rate of 142 beats per minute (bpm), respiratory rate of 23 pbm, oxygen saturation (in room air) of 83%, and oxygen bag reserve mask of 93%. We realized cardiac involvement during hospitalization, including sinus bradycardia, first-degree atrioventricular (AV) block, recurrent premature ventricular from tricuspid ring, atrial tachycardia (AT) rhythm with variable AV conduction block, increased heart rate with functional bundle branch block, and negative troponin. The patient was treated with medicines to control heart rate and admitted to the cardiac care unit (CCU). Next, the patient was intubated due to a worsening lung condition. Afterward, he was admitted to the intensive care unit (ICU) and died the next day. According to the literature, compromised cardiac vascular is the most common complications in hospitalized patients due to COVID-19 infection and has a higher mortality risk. Cardiac arrhythmias are additionally common clinical manifestations. These arrhythmias seem to be caused by inflammatory responses in the myocardium, electrolyte disorders, and hypoxia. Our patient showed that the COVID-19 virus might induce different types of arrhythmias.
