Irregularly irregular, wide complex tachycardia.
Impulses from the atria are conducted to the ventricles via either both the AV node and accessory pathway producing a broad fusion complex or just the AV node producing a narrow complex (without a delta wave) or just the accessory pathway producing a very broad 'pure' delta wave.
People who develop this rhythm and have very short R - R intervals are at higher risk of VF.
