Mel Herbert's classic tachyarrhythmia lecture. Watch this, then listen to the C3 Tachyarrhythmias episode, June 2017.
With a fib /wpw do uprefer sync or no synch with rapid rate. Ie delay and difficulty with syn recognition w rapid rate. . If no sync straight to 200j ???
I read previous nonsync should always go to 200j as lower energies more likely to trigger vfib. Is this your understanding
Polymorphic Vt is fast wide complex irregular - rule breaks - how often ?
What you do matters.
