.Cardiac affection in liver cirrhosis is a clinical condition characterized by impaired diastolic relaxation and contractility with electrophysiological abnormalities.~.Cirrhotic patients with cardiac abnormality have higher mortality rates compared to patients without cardiac affection.~The suggested pathophysiologic mechanisms of cardiac affection in cirrhotic patients are; alterations in the beta-adrenergic signaling pathway and, myocardial fibrosis formation, sympathetic nervous system activation and changes in ion channels.~.As a component of cardiac involvement in cirrhotic patients fragmented QRS complex and prolongation of the corrected QT interval has been documented in most of the cases with liver cirrhosis (LC) and its prevalence increases with the severity of the disease.~.Fragmented QRS (fQRS) is a convenient marker of myocardial scar evaluated by 12-lead electrocardiogram (ECG) recording. fQRS is defined as additional spikes within the QRS complex. In patients with CAD, fQRS was associated with myocardial scar detected by single photon emission tomography and was a predictor of cardiac events. fQRS was also a predictor of mortality and arrhythmic events in patients with reduced left ventricular function. The usefulness of fQRS for detecting myocardial scar and for identifying high-risk patients has been expanded to various cardiac diseases, such as cardiac cirrhosis, arrhythmogenic right ventricular cardiomyopathy, acute coronary syndrome. fQRS can be caused by zigzag conduction around the scarred myocardium, resulting in multiple spikes within the QRS complex .
