Overview

RVOT tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract. RVOT morphology refers to the characteristic pattern of this type of tachycardia on an ECG.

Pathophysiology

RVOT tachycardia is a type of monomorphic VT that originates from either the outflow tract of the right ventricle (the right ventricular outflow tract) or in some cases from the tricuspid valve annulus.

Associated Conditions

Uusally structural heart disease is absent, but RVOT tachycardia can occur in the context of arrhythmogenic right ventricular dysplasia (ARVD).

Natural History, Complications, Prognosis

RVOT tachycardia is generally not associated with sudden cardiac death.

Diagnosis

Physical Examination

In so far as structural heart disease is absent, there are no physical examination findings.

Electrocardiogram

Electrocardiographic characteristics include the following:
