Within what time frame should a 12-lead ECG be performed in a patient with chest pain?

• A. Within 10 minutes
• B. Within 30 minutes
• C. Within first 5 minutes
• D. Within 60 minutes

Answer: (C)

The key idea is that time matters a lot in chest pain to quickly identify a heart attack and start treatment. Getting a 12-lead ECG within the first few minutes allows you to detect a STEMI or other critical findings right away, so you can activate the cath lab or initiate reperfusion sooner. This rapid ECG helps minimize heart muscle damage and improves outcomes. Choosing within the first 5 minutes reflects the goal of immediate assessment—waiting longer delays diagnosis and treatment, which can worsen prognosis. While obtaining an ECG later (for example, after 10, 30, or 60 minutes) might eventually reveal the issue, it misses the opportunity for the fastest possible intervention. So, the best practice is to perform the 12-lead ECG as soon as chest pain is identified.
