*Monomorphic VT: all ventricular beats have the same configuration. | *'''Monomorphic VT''': all ventricular beats have the same configuration. | ||
*Polymorphic VT: the ventricular beats have a changing configuration. The RR interval is 180-600 ms (comparable to a heart rate of 100-333 bpm). | *'''Polymorphic VT''': the ventricular beats have a changing configuration.
