I now have excellent ECG images from authoritative textbooks. Here are your NEET PG ECG questions - give your answers!
π« NEET PG ECG Quiz - Real Textbook ECGs
β Question 1
A 42-year-old man presents to the ED with acute chest pain. Look at this ECG:
Findings: ST elevation in leads II, III, aVF AND lead V2. ST depression in V1, V2, V3.
Q: Which coronary artery is most likely occluded?
- A) Left Anterior Descending (LAD)
- B) Right Coronary Artery (RCA)
- C) Left Circumflex Artery (LCx)
- D) Left Main Coronary Artery
β Question 2
A patient presents with acute chest pain. The first ECG taken in the ED shows this pattern:
Findings: ST elevation in lead aVR greater than V1. Diffuse ST depression in other leads.
Q: What does ST elevation in aVR (greater than V1) suggest?
- A) Right ventricular infarction
- B) Posterior myocardial infarction
- C) Left main coronary artery occlusion or proximal LAD lesion
- D) Pulmonary embolism
β Question 3
Look at this precordial ECG showing deep symmetric T-wave inversions in V1-V6:
Findings: Prominent T-wave inversions in V1-V6 (anterior precordial leads).
Q: This pattern (Wellens sign) is classically associated with high-grade stenosis of which artery?
- A) Right Coronary Artery
- B) Left Anterior Descending Artery
- C) Left Circumflex Artery
- D) Posterior Descending Artery
β Question 4
Look at this ECG showing a wide-complex, irregularly irregular tachycardia with very short R-R intervals (as short as 240 ms, marked with asterisks *):
Q: This ECG pattern is seen in a patient with known WPW syndrome. What is the greatest risk of this arrhythmia?
- A) Stroke
- B) Progression to ventricular fibrillation and sudden death
- C) Complete heart block
- D) Cardiogenic shock
β Question 5
Look at this ECG showing P waves and QRS complexes that are completely dissociated from each other (ventricular rate slower than atrial rate):
Q: What is the MOST common cause of this type of AV block in adults?
- A) Inferior myocardial infarction
- B) Fibrosis/sclerosis of the conduction system (Lev's / Lenègre's disease)
- C) Lyme disease
- D) Digoxin toxicity
β Question 6 - Subendocardial vs Transmural Ischemia
The diagram shows two patterns:
- Panel A: ST vector directed inward (toward ventricular cavity)
- Panel B: ST vector directed outward (toward epicardium)
Q: Which pattern produces ST DEPRESSION in overlying leads?
- A) Panel B - transmural/epicardial ischemia
- B) Panel A - subendocardial ischemia
- C) Both patterns equally
- D) Neither - ST depression is unrelated to ischemia location
Take your time and give me your answers (e.g., "Q1-C, Q2-C, Q3-B" etc.)! I'll explain each one in detail. These are all real ECGs from Harrison's, Tintinalli's, and Braunwald's. πͺ
