What is the recommended time to recheck rhythm after a defibrillation shock?

• A. Immediately
• B. After about 1 minute
• C. About 2 minutes
• D. After 5 minutes

Answer: (C)

After a defibrillation shock, the priority is to restore perfusion with high-quality CPR and keep interruptions to a minimum. You should resume chest compressions immediately and recheck the rhythm after about 2 minutes of CPR. This 2-minute interval fits the standard CPR cycle in ACLS, giving time for coronary and cerebral perfusion pressures to build and for the shock to take effect if it’s going to. At the end of those two minutes, reassess to decide whether another shock is needed or to move on with the next steps. Rechecking sooner would interrupt CPR too early and reduce perfusion, while waiting much longer could delay appropriate treatment.
