BACKGROUND: COVID-19 causes severe illness and multi-organ dysfunction. An abnormal electrocardiogram is associated with poor outcome, and QT prolongation during the illness has been linked to pharmacological effects. This study sought to investigate the effects of the COVID-19 illness on the corrected QT interval (QTc). METHOD: For 293 consecutive patients admitted to our hospital via the emergency department for COVID-19 between 01/03/20 - 18/05/20, demographic data, laboratory findings, admission electrocardiograph and clinical observations were compared in those who survived and those who died within 6 weeks. Hospital records were reviewed for prior electrocardiograms for comparison with those recorded on presentation with COVID-19. RESULTS: Patients who died were older than survivors (82 vs 69.8 years, p455ms (males) and >465ms (females) (p = 0.028, HR 1.49 [1.04-2.13]), as predictors of mortality. QTc prolongation beyond these dichotomy limits was associated with increased mortality risk (p = 0.0027, HR 1.78 [1.2-2.6]). CONCLUSION: QTc prolongation occurs in COVID-19 illness and is associated with poor outcome. This article is protected by copyright. All rights reserved. |
