ECG — INFERIOR MI

Answer 20

ST elevation in II, III, aVF

ST depression in anterior leads

ECG — POSTERIOR MI

Answer 22

Enlarged R and T waves in V1-V3

+/- inferior/lateral MI

Question 23

ECG — LATERAL MI

Answer 23

ST elevation in I, aVL and V5-V6

ST depression in III and aVF

Question 24

What are the MAJOR criteria in Duke criteria?

Answer 24

Positive blood culture (typical organisms in 2+ cultures OR peristent positive cultures)

ECHO evidence (+ve echo or new valve regurgitation)

Question 25

What are the MINOR criteria in Duke criteria?

Answer 25

Risk factors (e.g. rheumatic fever) Fever >38 Vasculitic disease Blood culture/ECHO not meet major criteria

Question 26

How is Duke criteria used?

Answer 26

DEFINITE = 2 major OR 1 major + 3 minor OR 5 minor

Patient with heart failure is given some medication and subsequently develops hyperglycaemia - what is the causative drug?

Answer 27

Thiazide diuretic

Question 28
