QIC Acadian Ambulance Practice Test

Getting a 12-lead ECG quickly is essential because it allows early identification of a STEMI or other acute coronary syndrome, enabling rapid activation of reperfusion therapy and reducing heart muscle damage.

In EMS practice, the target is to obtain the 12-lead within ten minutes of first medical contact with the patient. This timeframe balances the need for speed with practical field considerations. Five minutes is often very challenging in real-world scenes, while waiting fifteen or twenty minutes would delay diagnosis and treatment, worsening outcomes.

So, ten minutes is the best answer because it represents a prompt, achievable standard for early ACS assessment in the field.
