Pharmacotherapy in inherited and acquired ventricular arrhythmia in structurally normal adult hearts.

: Ventricular arrhythmias are often seen in association with structural heart disease. However, approximately a tenth of affected patients have apparently normal hearts, where such arrhythmias typically occur in young patients, are sometimes inherited and can occasionally lead to sudden cardiac death (SCD). Over the past two decades, increased understanding of the underlying pathophysiology resulted in improved targeted pharmacological therapy.
