Patients with long QT syndrome exhibit excessively prolonged right ventricular monophasic action potentials and abnormally long effective refractory periods.
May guide mechanistic inquiry in long QT syndrome; leaves open generalizability from this single case.
In 3 patients with the long QT syndrome, one caused by quinidine and 2 of congenital origin, right ventricular monophasic action potentials were excessively prolonged and of varying shapes in different recording sites. In addition, effective refractory periods of the ventricular muscle were abnormally long.
