Podcast #319: Cardiac Arrest Survival Factors

Author: Aaron Lessen, MD

Educational Pearls:

• Shockable rhythms like V-fib or V-tach have a better prognosis than patients with PEA or asystole.

• Recent study has shown an initial electrical frequency in PEA between 10-24/min had worse outcomes than PEA with initial rhythm over 60/min.

• Patients with an initial electrical frequency in PEA over 60/min did just as well as patients with shockable rhythms. Of them, there was a 22% survival rate with 15% having a good neurologic outcome.
