I've never heard amiodarone kills people with WPW. Can you post some articles that you have read?
From what I know about WPW, it isn't a subset of atrial fibrillation as you posted. WPW is a re-entry tachycardia more similar to SVT.
As you know, ACLS guidelines are for emergencies. I could definitely see treating unstable WPW with amiodarone if urgent treatment was needed. Cardioversion could also be a good option if patient was very unstable. Just because a treatment is in the ACLS guidelines doesn't mean that it is what is recommended for the patient long-term.
I was always taught that the definitive treatment of WPW was an ablation to interrupt the pathway and that drug treatments were less desirable for recurrent, symptomatic WPW. A girlfriend of mine has this (she wore a holter for a week, and she was having 5-10 minutes episodes of HR's in the 180-200 range) and they put her on a beta-blocker which has reduced her episodes significantly. She is only 30 and didn't want an ablation due to the potential risk of needing a pacemaker afterward. I actually hadn't heard of procainamide as a drug of choice for WPW. http://www.americanheart.org/present...dentifier=4785
