Abstract

Patients with Romano-Ward Syndrome show abnormal long QT-intervals in ECG and have a high risk of sudden cardiac death. The QT-syndrome is a pure electrophysiological disease in otherwise normal hearts. The underlying electrophysiological mechanism triggering ventricular flutter/fibrillation in these patients is an uneven depolarization and repolarization of the myocardium and the specialized conducting tissue (Schwartz et al., 1975). Like in other autosomal dominant inherited diseases expression of symptoms is variable among family members. Up to now a specific method for the discrimination of these high-risk patients does not exist.
