In addition, the new report proposes major changes in the diagnostic criteria for the two most common primary arrhythmia syndromes: long QT syndrome (LQTS) and Brugada syndrome.
Groups at increased risk for torsades de pointes are those with known prolongation of the QT interval, history of torsades de pointes, congenital long QT syndrome, bradyarrhythmias, or uncompensated heart failure, as well as those on drugs known to prolong the QT interval, those with ongoing proarrhythmic conditions, those with clinically significant bradycardia, and patients treated with class IA (quinidine, procainamide) or class III (dofetilide, amiodarone, sotalol) antiarrhythmic drugs.
