Polymorphous ventricular tachycardia (Torsade de pointes). | |||
This is a form of VT where there is usually no difficulty in recognising its ventricular origin. | |||
wide QRS complexes with multiple morphologies | |||
changing R - R intervals | |||
the axis seems to twist about the isoelectric line | |||
it is important to recognise this pattern as there are a number of reversible causes | |||
heart block | |||
hypokalaemia or hypomagnesaemia | |||
drugs (e.g. tricyclic antidepressant overdose) | |||
congenital long QT syndromes | |||
