Noncoronary cusp (NCC) ventricular tachycardia is a rare form of monomorphic outflow tract tachycardia, and its electrocardiographic and electrophysiological characteristics have not been well described previously. The NCC should be considered for catheter ablation if attempts to eliminate ventricular tachyarrhythmia were unsuccessful in the other common anatomical sites of the left ventricular outflow tract.
