{{Information
|Description = A 45 year old lady with palpitations and history of chronic renal failure
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
other causes of long QT (e.g. IHD)
