Dr. Jesus Yap answered

Protection: You must have the type of Long QT syndrome (type1) that the risk of a serious and potentially fatal arrhythmia can be triggered by bouts of emotional stress or by exercise . This can be prevented by beta blockers. Beta blockers block the surge of adrenaline that occurs with those 2 conditions
