Ventricular tachycardia should be described by type (monomorphic or polymorphic), duration (sustained or non-sustained) and heart rate — i.e. monomorphic VT non-sustained at a heart rate of 220 ...

Acceleration to a faster monomorphic VT, polymorphic VT, or VF, is uncommon when ATP is applied to slow VT (CL < 300-320 ms). The lack of a consistent definition of acceleration renders comparison ...
