Which leads of the ECG correspond to the inferior wall of the heart?

The inferior wall of the heart is primarily supplied by the right coronary artery in most individuals, and this area is represented on the electrocardiogram (ECG) by leads II, III, and aVF. These leads are positioned such that they capture electrical activity from the inferior aspect of the heart, making them critical for identifying any issues or changes in this region.

Lead II records the electrical activity from the right arm to the left leg, while lead III records from the left arm to the left leg, and aVF measures the activity from both arms towards the foot. Therefore, any ischemia or infarction involving the inferior wall will typically show significant changes in these leads, such as ST-segment elevation or depression.

In contrast, the other choices either represent different areas of the heart or do not capture the specific inferior wall area effectively. Understanding the specific leads that correspond to different anatomical regions allows for more accurate diagnosis of cardiac conditions, making this knowledge essential for interpreting ECGs in clinical practice.
