The Ashman phenomenon is a specific type of this condition. A potentially lethal form of this condition occurs in Brugada syndrome. Drugs used to treat this condition are categorized using the Vaughn-Williams classification. This condition can be caused in Lown-Ganong-Levine syndrome by the creation of an accessory conduction pathway. A similar accessory pathway called the bundle of Kent also leads to this condition in a pre-excitation syndrome known as Wolff-Parkinson-White syndrome. This condition may be treated by sodium-channel blockers such as flecainide and procainamide. The drug Sotalol, which length- ens the QT interval, is a beta blocker which treats this condition. Atrial flutter and atrial fibrillation are types of this condition. It also includes tachycardias and bradycardias, which involve rates below 60 bpm or above 100 bpm. For 10 points, name this condition in which the heart beats irregularly.
