Long QT interval

Sudden syncope or pseudo-seizures while exercising or during periods of stress or a family history of sudden death should raise suspicion for LQTS and prompt ECG evaluation. Unfortunately, a normal resting QTC does not reliably exclude LQTS, although exercise testing may provoke prolongation of the QTC.2 Genetic testing may potentially enhance diagnostic reliability in the future, although at present genotyping uncovers no mutation in approximately 30% of affected individuals.
