Why is early 12-lead ECG important in post-arrest care?

• A. It is unnecessary after ROSC
• B. Identify STEMI or other acute coronary syndromes and guide urgent reperfusion decisions
• C. It only confirms rhythm
• D. It should be delayed until after imaging

Answer: (B)

After ROSC, getting a rapid 12-lead ECG is essential because a large number of arrests are due to an acute coronary occlusion. The ECG can reveal STEMI or other acute coronary syndromes, which dictates urgent reperfusion decisions such as activating the cath lab for PCI or considering thrombolysis if PCI isn’t immediately available. Early reperfusion can limit heart muscle damage and improve survival and neurologic outcome. The ECG provides information beyond just rhythm—it identifies ischemia or infarction that needs immediate treatment. It shouldn’t be delayed for imaging, and it isn’t just about confirming rhythm; even if the rhythm is stabilized, the heart may still be ischemic and require rapid intervention.
