In ACLS, rhythm checks are typically performed every 2 minutes?

• A. About 2 minutes
• B. Every 1 minute
• C. Every 30 seconds
• D. Every 5 minutes

Answer: (A)

Rhythm checks are timed to align with the CPR cycles used during ACLS. After about two minutes of continuous chest compressions, you briefly pause to reassess the heart rhythm with the monitor/defibrillator. If a shockable rhythm is present, you deliver a shock and then resume high-quality CPR immediately, starting the next two-minute cycle. This cadence minimizes interruptions to CPR while still allowing timely defibrillation when needed. That’s why the best answer is about two minutes. Checking every minute would disrupt the CPR cadence, checking every 30 seconds would cause unnecessary pauses, and waiting five minutes would delay important rhythm reassessment and potential defibrillation.
