Abstract
-
Wolff-Parkinson-White(WPW) syndrome is characterized by electrographic evidence of ventricular preexcitation, which predisposes to supraventicular arrhythmias. Familial occurrence of WPW syndrome is uncommon. We observed two affected siblings in a family. Five members of the family underwent 12-lead electrocardiography and echocardiography. Although known genetic abnormality of the 7q34-q36(PRKAG2) for the familial WPW syndrome was evaluated, the mutation was not detected in this family. Other unknown mutations responsible for this familial WPW syndrome were suggested.
