Sick rhythms

Remember that in atrial fibrillation with a pre-excitation pathway such as WPW you can distinguish it by it’s irregular rate, rate >200 and in some places up to 300 which is not typical of atrial fibrillation with LBBB and subtle variation in QRS duration from beat to beat which is not seen in LBBB.

Treat these patients with IV procainamide or cardioversion. AVOID IV calcium channel blockers and digoxin as these can precipitate ventricular fibrillation.
