الإجابة: C. ECG
Typical ischaemic chest pain (at rest, >30 min, radiating to the left arm, sweating, dyspnoea) = suspected ACS. The 12-lead ECG is the first test, done within 10 minutes of arrival, because ST elevation sends the patient straight to reperfusion. CXR and CT chest are not the first step, and myocardial perfusion imaging belongs to stable-angina work-up, not acute pain.
