Highlights the importance of recognizing inherited prolonged Q-T syndrome and its treatment with beta-blockers, particularly in the context of anaesthetic management.
Perioperative recognition of prolonged QT syndrome may reduce risk; level 5 evidence leaves optimal beta-blocker protocols open to prospective trials.
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.
