Question 1

T-wave inversion is often found in leads:

A. V1-V3
B. V2-V4
C. V4-V5
D. V5-V6

Answer 1

A. V1-V3

Question 2

T-wave inversion is a NORMAL finding in what subset of the population?

A. African-Americans
B. Females
C. Pediatrics
D. African-American males

Answer 2

C. Pediatrics

Question 3

What age-related change causes t-waves to become positive in leads V1-V3?

Answer 3

Enlargement of the left ventricle

Question 4

How does one differentiate between ischemia vs. persistent juvenile T-waves?

Answer 4

Ischemia:

• Symmetry in T-waves
• Deeper than 3 mm
• If inversion extends to V4-V6

PJTW:

• Asymmetric t-waves
• Less than 3 mm
• Usually localized to V1-V3

Question 5

Insert some ECGs

Answer 5

OK
