[SCD Symposium]

Dear Dr. Costa, by our experience a beta blockers or Na blockers in pts with 
LQTS not to influence on the prolongation of QT interval. One of the sign of 
nonffectivness of the antyarrhythmic drug threapy is repeat syncope or 
presyncope  under therapy.  It is also the indication for ICD threapy as 
well as  other proarrhythmogenic signs rest ECG or Holter monitoring - T 
wave alternans, ventricular arrhythmia by my mention.  Of course it will be 
useful genetic suggesting of the LQT3 for indication to Na blockers therapy.
Sincerely yours
Dr. Leonid Makarov, Moscow, Russia
