Study of left and right ventricular function in Romano-Ward syndrome.

Electrical alternans of TU wave in Romano-Ward syndrome.

A case is presented in which an exceptional electrical alternans of the TU wave occurred in association with the Romano-Ward syndrome. This appears to be the first reported example of this association. Ventricular fibrillation was documented during the syncopal attacks. There was no evidence of abnormality of the serum electrolytes.

Romano-Ward Long QT Syndrome Analysis of 23 Families

Background The Romano-Ward long-QT Syndrome (LQTS) is an autosomal dominant inherited trait characterized by prolonged QT interval on ECG, life-threatening arrhythmias, syncope, and sudden death in affected individuals. A gene responsible for this disorder has been shown to be linked to the Harvey ras-1 locus (H-ras-1) DNA marker on the short arm of chromosome 11 (llp) in 7 families. The purpos...

A recessive variant of the Romano-Ward long-QT syndrome?

BACKGROUND The congenital long-QT syndrome (LQTS) is a genetically heterogeneous disease characterized by prolonged ventricular repolarization and life-threatening arrhythmias. Mutations of the KVLQT1 gene, a cardiac potassium channel, generate two allelic diseases: the Romano-Ward syndrome, inherited as a dominant trait, and the Jervell and Lange-Nielsen syndrome, inherited as an autosomal rec...

Epilepsy: a presentation of the Romano-Ward syndrome.

Syndrome of Left Ventricular - Right Atrial

Two similar cases of unusual congenital anomalies of the heart are presented, in which there existed a direct communication between the left ventricle and the right auricle through a defect involving the membranous portion of the interventricular septum with defective formation of the medial leaflet of the tricuspid valve. Data obtained at catheterization, operative and postmortem findings are ...
