Prolonged Qt

Recent reports have suggested an increased risk of QT prolongation and subsequent life-threatening ventricular arrhythmias, particularly torsade de pointes, in patients with coronavirus disease-2019 (COVID-19) treated with hydroxychloroquine and azithromycin. In this article, we report the case of a 75-year-old female with a baseline prolonged QT interval in whom the COVID-19 illness resulted in further remarkable QT prolongation (>700 ms), precipitating recurrent self-terminating episodes of torsade de pointes that necessitated temporary cardiac pacing. Despite the correction of hypoxemia and the absence of reversible factors, such as adverse medication effects, electrolyte derangements, and usage of hydroxychloroquine/azithromycin, the QT interval remained persistently prolonged compared with the baseline with subsequent degeneration into ventricular tachycardia and death. Thus, we highlight that COVID-19 illness itself can potentially lead to further prolongation of QT interval and unmask fatal ventricular arrhythmias in patients who have a prolonged QT and low repolarization reserve at baseline.

We report a case of a 88-year-old female, admitted to the hospital with tachycardia, chest pain and dyspnoea. ECG revelead a recent new-onset atrial fibrillation. A pharmacological cardioversion with amiodarone was performed, and restoration of sinus rhythm was obtained. Sotalol for rhythm control was administered. On the eighth day after the admission, she presented with severe dyspnoea and hypotension. An ECG revelead torsade de pointes, associated with prolonged QT interval. Several factors are involved in determining dyspnoea. ECG, although not specific, is an important instrument that supports clinicians in assessment of dyspnoea.
