12-lead ECGs should be obtained within 10 minutes when indicated.

Explanation:
Time is critical when chest pain or suspected acute coronary syndrome appears. A 12-lead ECG quickly identifies STEMI, guiding immediate treatment decisions and activation of reperfusion pathways. The standard target is to obtain the ECG within ten minutes of patient contact or arrival. This timing balances practicality with the need for rapid diagnosis to minimize heart muscle damage. Getting it sooner helps, but ten minutes is the commonly accepted benchmark. Waiting longer—fifteen or twenty minutes—can delay definitive treatment and worsen outcomes. While five minutes is ideal in some settings, ten minutes is the typical standard used in many EMS protocols.
