Fast Broad Irregular rhythms

This means WPW with AF.

The thing to remember is that all the stuff you would normally use for any fast rhythm cannot be used in patients with WPW to slow that rhythm down - you can't use A, B or C (adenosine, beta-blockers, or calcium channel blockers) - because they will all convert the AF to 1:1 conduction and therefore VF. So, in WPW patients there is no such thing as rate control, only rhythm control with amiodarone and procainamide.
