Idiopathic ventricular tachycardias
Most are outflow tract tachycardias and most of those are right ventricular. They are unique in that while they tend to be benign they may cause tachycardia mediated DCM and are amenable to ablation. (They may respond to calcium blockers too but leave that to the experts). Also don't forget that right ventricular cardiomyopathy may manifest as RV tachycardia. This review focuses on RVOT.
