What leads indicate lateral wall ischemia?

What leads indicate lateral wall ischemia?

• A. V3 and V4
• B. Leads II, III, aVF
• C. Lead I, aVL, V5, V6
• D. Atrial and ventricular leads

Answer: (C)

Lateral wall ischemia refers to a lack of blood flow to the outer wall of the heart, particularly the left side. The leads that are used to assess the lateral wall are positioned in such a way that they can pick up electrical activity from that specific area. Lead I and aVL are both positioned to monitor the left atrium and the left lateral aspect of the left ventricle. V5 and V6 are located in the left precordial region, which also covers the lateral wall of the left ventricle. These leads provide critical information about the electrical activity in the lateral wall, thus making them particularly effective for detecting ischemia in that area. In summary, the combination of Lead I, aVL, V5, and V6 collectively allows for a thorough evaluation of the lateral wall of the heart, making them the correct choice for identifying lateral wall ischemia.
