Prolonged QT interval and cardiac arrest after a single dose of amiodarone in a woman with Turner's syndrome.
Low-dose QT-prolonging drugs may have detrimental effects on women with Turner's syndrome. Preventive measures would be to use potential QT-prolonging drugs with precaution and ensure that both before and during treatment, ECGs are evaluated and drug treatment stopped if the QT interval increases.
