Which ECG leads typically reflect changes in the inferior wall of the heart?

The inferior wall of the heart is primarily supplied by the right coronary artery in most individuals, and the electrical activity in this area is best reflected in specific ECG leads. Leads II, III, and aVF are oriented in such a way that they capture the electrical signals coming from the inferior portion of the heart effectively.

Lead II looks at the heart from the left leg towards the right arm, while lead III examines the left leg from the left arm, and lead aVF looks from the foot towards the head. This positioning allows them to pick up signals generated from the inferior wall, making any abnormalities in this area more discernible in these leads.

Understanding the anatomy and blood supply of the heart is crucial for correctly interpreting the ECG findings. For example, while the other leads mentioned in the options provide insights into various regions of the heart, they do not primarily reflect changes in the inferior wall.
