Which one of these options describes the 'Electrical phase' in the resuscitation process?

The 'Electrical phase' in the resuscitation process refers to the critical early moments following cardiac arrest, specifically from 1 to 4 minutes. During this phase, the heart has not sustained significant damage, and its cells still have the potential to recover with effective CPR and defibrillation. The focus during this period is on restoring a viable rhythm as quickly as possible because the cells are still able to respond to electrical stimuli.

Within the context of the phases of cardiac arrest, maintaining a rapid intervention can greatly increase the chances of successful resuscitation. The electrical phase is characterized by the heart's electrical activity being primarily affective, before cellular metabolism begins to deteriorate, which typically happens as time progresses beyond this phase. This is why timely intervention is critical, as the chances of survival and the potential for good neurological outcomes start to decline significantly after the first few minutes of cardiac arrest.
