Ventricular arrhythmias in normal hearts.
Ventricular tachycardia in the structurally normal heart accounts for approximately 10% of cases. Although the overall prognosis is relatively good, with a benign course in most patients, these arrhythmias can lead to significant symptoms. Our understanding of these arrhythmias has progressed significantly, leading to effective therapies targeting their underlying mechanism. In many cases, catheter ablation is successful and the therapy of choice in patients who have sufficient symptoms. This article reviews outflow tract, idiopathic left ventricular, and automatic ventricular tachycardias.
