What leads are used to assess the inferior wall of the heart?

The inferior wall of the heart is primarily assessed using leads II, III, and aVF. These leads are arranged in such a way that they provide a view of the electrical activity coming from the inferior portion of the heart, which corresponds to the area primarily supplied by the right coronary artery in a majority of individuals.

Leads II and III capture the electrical impulses as they move from the upper parts of the body towards the lower parts, while aVF is oriented towards the feet, providing a direct view of the inferior wall. This makes them ideal for diagnosing conditions affecting the inferior portion of the heart, such as inferior wall myocardial infarctions or other cardiac issues.

In summary, leads II, III, and aVF are closely aligned with the anatomical and physiological setup of the heart's inferior wall, making them essential for proper assessment.
