*'''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.

Ventricular tachycardia can be difficult to diagnose when confronted with a wide complex tachycardia. A seperate chapter deals with [[Approach_to_the_Wide_Complex_Tachycardia|ECG algorithms to analyse wide complex tachycardias]]. | |||
