The prolonged Q-T syndrome. A review with anaesthetic implications and a report of two cases.

Inherited prolongation of the Q-T interval is associated with syncopal attacks due to ventricular arrhythmias, which, if untreated, are often fatal at an early age. The condition is reviewed and the anaesthetic management of two patients with the syndrome presented. The importance of recognition of the syndrome and its treatment with beta-blockers is stressed.
