Correlation between QT-interval Duration and Treatment with Propranolol in Patients with Liver Cirrhosis

Abstract

We studied the effect of chronic treatment with propranolol on QT-interval duration in a group of patients with liver cirrhosis. It is known that they may have a secondary cardiac disease, the cirrhotic cardiomyopathy. As several studies have reported a reduction in QT-interval in these cases, we investigated this, knowing that there is frequently a prolonged QT-interval in cirrhotic cardiomyopathy.
