First step in managing a suspected STEMI?

Explanation:
In suspected STEMI, the most urgent step is to obtain a 12-lead ECG right away to detect ST-segment elevations and confirm the diagnosis. This ECG tells you if the event is a STEMI and thus whether urgent reperfusion therapy (PCI or thrombolysis where PCI isn’t available) is needed. Time is critical because myocardial tissue salvage depends on how quickly reperfusion can be achieved. Starting thrombolytics or giving morphine before you have ECG confirmation can be inappropriate or delay definitive care. A chest X-ray, while sometimes helpful for other reasons, does not diagnose STEMI and should not be the first action. So the immediate priority is the 12-lead ECG to establish the STEMI diagnosis and guide next steps.
