AMLS Cardiac Emergencies 1

Question 1

Which ECG finding is most consistent with an acute ST-elevation myocardial infarction (STEMI) in the inferior leads?

Accepted Answer

ST elevation in leads II, III, and aVF

Answer

Inferior STEMI presents with ST elevation in leads II, III, and aVF, reflecting ischemia of the right coronary artery territory.

Question 2

A patient presents with sudden-onset tearing chest pain radiating to the back. Which condition should be suspected first?

Accepted Answer

Acute aortic dissection

Answer

Tearing or ripping chest pain radiating to the back is the classic presentation of acute aortic dissection.

Question 3

What is the primary goal of early reperfusion therapy in STEMI management?

Accepted Answer

Restore coronary blood flow to salvage myocardium

Answer

Early reperfusion aims to restore coronary blood flow to limit infarct size and salvage viable myocardium.

Question 4

Which rhythm is most commonly the initial rhythm seen in sudden cardiac arrest due to cardiac etiology?

Accepted Answer

Ventricular fibrillation

Answer

Ventricular fibrillation is the most common initial rhythm in sudden cardiac arrest of cardiac origin and is shockable.

Question 5

A patient with chest pain has a 12-lead ECG showing new left bundle branch block. How should this be managed?

Accepted Answer

Treat as STEMI equivalent and activate cath lab

Answer

New LBBB with chest pain is treated as a STEMI equivalent, requiring emergent cardiac catheterization.
