The Romano-Ward syndrome: a case presenting as near drowning with a clinical review.

Patients with the Romano-Ward syndrome, a form of congenital long Q-T syndrome (LQTS), present with syncopal episodes and are at risk for sudden death. Patients with LQTS may be misdiagnosed if the physician is unaware of this entity. The risk of sudden death makes recognition important so that appropriate therapy can be initiated. A case is discussed in which the patient presented following a near-drowning episode. Family history revealed a familial "seizure disorder." After analysis of the patient's and father's ECGs, the diagnosis of Romano-Ward syndrome was made. A review of the literature was done, concentrating on presentation, pathophysiology, electrocardiographic findings, etiology, diagnosis, prognosis, and treatment of congenital LQTS. This paper is presented to emphasize the importance of physician awareness of LQTS because of the risk of sudden death. Proper diagnosis can lead to treatment that is effective in reducing mortality by more than 90%.
