right ventricular outflow tract ventricular tachycardia ecg image

Diagnosis- RVOT ventricular tachycardia (RVOT – Right ventricular outflow tract)


1. The first two beats are wide complex. Then sinus rhythm is seen. Wide complex tachycardia recurs after 5 sinus beats. The last beat is a sinus beat.

2. P waves dissociated from the QRS can be seen in the bottom rhythm strip (lead II) in the second group of wide complex beats- so the tachycardia is VT.

3. LBBB pattern + inferior axis. This is the characteristic pattern in RVOT VT. Inferior axis is inferred from the first two wide complex beats seen in leads I, II and III.
