Belhassen VT with capture beat

Belhassen ventricular tachycardia ecg image

Diagnosis- Belhassen’s tachycardia (posterior fascicular ventricular tachycardia)


1. QRS is wide, but not very wide, the width being 120 msec. This makes it difficult to differentiate whether this is VT or SVT.

2. Capture beat indicating that it is VT, not SVT.

3. RBBB + left axis deviation, the characteristic pattern in Belhassen’s tachycardia.
