Surdo-cardiac syndrome: incidence among children in schools for the deaf

This is a report on a survey of 1126 deaf children in three schools for the deaf in the Province of Ontario. One case of the surdo-cardiac syndrome previously reported is included. There were four other children who had a history of syncope but no prolongation of the Q-T interval on the ECG. It is possible that these may represent a variant of the syndrome. Five more children had a prolonged Q-T interval but no fainting spells.
