This ECG meets two criteria for ventricular tachycardia. AV dissociation appears to be present. Examine the rhythm strip in lead V1 and intermittently a P wave will correspond just prior to the QRS complex. The QRS is in a right bundle branch block pattern and the R is taller than the R' which is one of the morphology criteria to diagnose ventricular tachycardia. Note that there is potentially a fusion beat on this ECG as well (10th beat from the left), however it does not have a classic appearance for this finding (see Ventricular Tachycardia Review below).
