It depends on the context.Originally posted by: LordSegan
^^ It's my understanding that most arrest rythems are shockable though yes? Before a person goes into asystole, they usually go into V-fib first...
In the context of sudden unexpected cardiac arrest in adults, shockable rhythms are relatively common.
In cardiac arrests in children, or in adults, due to a non-cardiac illness or trauma, shockable rhythms are the exception, and asystole or PEA are much more common. As the treatment in these cases, is reversal of the underlying cause for the cardiac arrest, rather than restoring cardiac rhythm, the outcome in such situations is very poor.
