right ventricular outflow tract ventricular tachycardia ecg image

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

Pointers-

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.

Comments are welcome!
