In terms of the leads “looking at” the hea walls, which of the following is an odd one out?
Correct Answer: Lead aVL
Description: Leads II, III, and aVF are called "inferior leads". These leads have their positive (or exploring) electrode on the foot. These 3 leads look to the hea from below; i.e., they are directly looking at the inferior wall of the hea. Any ECG changes in these 3 leads will be reflective of pathology of the inferior wall (e.g., inferior wall MI). avL looks at the hea from left side, hence it is the odd one out.
