These arrhythmias are due to mutations in ion channels or structural proteins and include ventricular tachyarrhythmias due to long and short QT syndromes, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia (VT). However, the basis for the most common form of idiopathic ventricular arrhythmia, which originates from right or left… CONTINUE READING
