Which test would be immediately ordered for a Cardiac Workup in the ED?

• A. EKG
• B. CXR
• C. Troponin
• D. CBC and BMP

Answer: (A)

Evaluating a patient with potential cardiac trouble in the ED begins with an ECG because it directly shows the heart’s electrical activity and can reveal ischemia, arrhythmias, or ST-segment changes within minutes. This fast information is crucial for guiding urgent treatment decisions, such as starting anti-ischemic therapy or activating a reperfusion pathway. While troponin testing is essential for confirming myocardial injury, it may be normal at presentation and rises later, so it cannot replace the early ECG. Chest X-ray and basic labs like CBC and BMP provide helpful context and data about other issues or overall health, but they don’t assess the heart’s electrical status or acute ischemia as quickly as an ECG.
