Ventricular tachycardia - fascicular

Ventricular tachycardia is an arrhythmia that is fast and originates from the ventricles. It features wide QRS complexes. It can be either sustained (>30 sec) or nonsustained, monomorphic or polymorphic. It can be very difficult to tell apart from a supraventricular tachycardia with aberrant conduction.Fascicular ventricular tachycardia is a less common form of VT that originates within the left ventricle. It is more narrow than most other forms of VT, with a shorter RS interval of 60-80 msec. It classically has a RBBB pattern and occurs in young healthy patients. It is also known as Fascicular tachycardia, Belhassen-type VT, verapamil-sensitive VT or infrafascicular tachycardia.
