QuestionChoice
These leads are specifically oriented to detect changes in the inferior part of the heart, making them critical for the diagnosis of an inferior STEMI.

ST-segment elevation in leads II, III, and aVF
QuestionChoice
ST-segment elevation in leads I, aVL, and aVR can indicate high lateral involvement or possible left main coronary artery disease.

d
ST-segment elevation in leads I, aVL, and aVR
QuestionChoice
ST-segment elevation in leads I and aVL usually suggests high lateral wall involvement, while V1-V6 is associated with anterior wall involvement.

c
ST-segment elevation in leads I, aVL, and V1-V6
QuestionChoice
ST-segment elevation in the precordial (chest) leads (V1-V6) typically indicates anterior myocardial infarction, not an inferior STEMI.

b
ST-segment elevation in leads V1-V6
QuestionChoice
T-wave inversion in the precordial leads may be seen in various conditions and could be a precursor sign for a STEMI, but is not the classic ECG change associated with an acute STEMI, especially an inferior one.
