Paradigm shift in cardiac arrest rhythm and resuscitation

What resuscitation strategies targeted toward pulseless electrical activity (PEA)/asystole would be successful in preventing cardiac arrest (CA)? Furthermore, what are animal models of PEA/asystole, what is responsible of this major shift in the underlying rhythm of CA, and what is the phenotype?

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Compelling Question (CQ)

Details on the impact of addressing this CQ or CC

There is a critical need to address continuous shift in the primary rhythm of CA from VT/VF to PEA/asystole with new strategies to improve survival.

Feasibility and challenges of addressing this CQ or CC

Data from major registries, such as ROC, CARES and other provide the needed population base and platform to analyze existing strategies, explore and develop and test new resuscitation strategies.
With the continuous decline in VT/VF proportion as the primary rhythm leading to cardiac arrest (CA), pulseless electrical activity (PEA) and asystole have become the dominant rhythms in CA. In early 70's VT/VF constituted more than half of the CA, which currently is ~ 28%. Major effort and defibrilation and resuscitation strategies have been successfully targeted toward VT/VF. The survival of PEA/asystole is dismal.
