OBJECTIVE Long QT syndrome (LQTS) is a cardiac channelopathy predisposing to syncope and sudden death secondary to LQT-triggered ventricular arrhythmias. Long QT syndrome has been regarded as a purely electrical disease. Recent reports have shown by echocardiography that LQTS patients have contraction abnormalities that are associated with cardiac arrhythmias. The purpose of this study was to determine the spectrum and prevalence of echocardiographic anomalies in a large cohort of patients… CONTINUE READING
