BACKGROUND: QT-interval prolongation is considered the electrophysiological hallmark of cirrhotic cardiomyopathy. However, the significance of QT-interval prolongation and how it is affected by liver transplantation (LT) remains unclear. METHODS: Consecutive inpatients undergoing LT between 2010 and 2017 at a state-wide liver transplant center in Australia were included. Preoperative, early postoperative and long-term follow-up corrected QT-intervals (QTc) were manually measured by a cardiologist. QTc was calculated using the Bazett formula and QTc ≥440 milliseconds (ms) was considered prolonged. RESULTS: Overall, 1111 ECG tracings among 408 patients (mean age 57 ± 12 years) were assessed.
