What is Belhassen’s VT?
Belhassen’s VT: Idiopathic Fascicular Ventricular Tachycardia
Heart Disease FAQ / Brief Review
Abstract: Belhassen’s VT is idiopathic fascicular ventricular tachycardia originating from the left posterior fascicle. It is responsive to verapamil and is an ablatable VT.
On Belhassen’s VT for Heart Disease FAQ
Belhassen’s VT is a fast rhythm originating from the left ventricle. VT is short for ventricular tachycardia. It is named after the person who described it. Belhassen’s VT originates from a branch of the left bundle branch known as the posterior fascicle. Hence it is also known as posterior fascicular tachycardia. To be more exact, its name is idiopathic posterior fascicular tachycardia. Idiopathic means of unknown origin, indicating that it is not secondary to a known cause like a heart attack with loss of blood supply to the region. It manifests in the ECG with a pattern simulating right bundle branch block with left axis deviation of the QRS complex.
More on Belhassen’s VT
Belhassen and associates described a ventricular tachycardia responding to verapamil,1 unlike the usual ventricular tachycardias which respond to lignocaine. It may be noted that verapamil is conventionally a drug used for treatment of supraventricular rather than ventricular tachycardia. Even though other authors had reported on ventricular tachycardias with relatively narrow QRS complex originating from the posterior fascicle,2 it was Belhassen and colleagues...
