ECG

Question 1

What ECG changes are associated with Anteroseptal territory?

Answer 1

V1-V4

Anteroseptal changes indicate issues with the left anterior descending artery.

Question 2

What ECG changes correspond to the Inferior territory?

Answer 2

II, III, aVF

Inferior changes are typically related to the right coronary artery.

Question 3

Which leads are involved in Anterolateral ECG changes?

Answer 3

V1-6, I, aVL

Anterolateral changes are often due to the proximal left anterior descending artery.

Question 4

What leads are associated with Lateral changes in ECG?

Answer 4

I, aVL +/- V5-6

Lateral changes are usually due to the left circumflex artery.

Question 5

Which coronary artery is primarily associated with Anteroseptal changes?

Answer 5

Left anterior descending

This artery supplies blood to the anterior wall of the heart.

Question 6

How is Posterior infarction confirmed on an ECG?

Answer 6

ST elevation and Q waves in posterior leads (V7-9)

These findings indicate damage to the posterior wall of the heart.

Question 7

What does a new left bundle branch block (LBBB) indicate?

Answer 7

It may point towards a diagnosis of acute coronary syndrome

LBBB can mask or mimic other ECG changes, complicating diagnosis.

Question 8

Which artery is primarily associated with Inferior ECG changes?

Answer 8

Right coronary artery

This artery supplies the inferior wall of the heart.

Question 9

Which artery is associated with Lateral changes in ECG?

Answer 9

Left circumflex artery

Lateral changes may also involve the right coronary artery.

Question 10

What ECG changes are seen in posterior coronary territories?

Answer 10

V1-V3

Usually left circumflex, also right coronary artery
