The patient appears uncomfortable. She is pale, diaphoretic, and clutching the center of her chest. While obtaining vital signs, the nurse says he's concerned about the patient and asks for your orders. The patient's blood pressure is 90/63 mm Hg, heart rate is 110 beats/minute, and oxygen saturation is 89% on room air. You call for the rapid response team and tell the nurse to start supplemental oxygen.

Question: As the ECG is being obtained, what steps do you take to stabilize the patient?

While you wait for help to arrive, you can start taking the following steps.

Check out the flowcharts below for a preview of how you and the rapid response team might proceed if the ECG shows a STEMI or signs of pulmonary embolism. For more detail, see “Management of chest pain.

Consult cardiology immediately for management (e.g., emergency revascularization) of acute STEMI.

Practice: Do you see what I see?toggle arrow icon

Reading an ECG quickly and correctly is an important skill to hone, since you'll often be the first one handed the ECG to rule out serious abnormalities. STEMI is a diagnosis you won't want to miss, and the faster you can diagnose it, the higher the likelihood of a good outcome for the patient.

ECG practice

Test your eyes on the following ECGs. Identify the pertinent findings, then apply the AMBOSS overlay to check your work.

You can also read up on ECG changes in STEMI, STEMI-equivalent ECG findings, ECG changes in NSTEMI/unstable angina, and high-risk ECG findings in PE.
