Which chest leads are mentioned together as being associated with the sternum in the material?

• A. V1 and V2
• B. V2 and V4
• C. V3 and V5
• D. V4 and V6

Answer: (B)

In the chest leads, the placement of V2 and V4 sits closest to the sternum on the anterior chest wall. V2 is at the left sternal border, right beside the sternum, and V4 sits in the fifth intercostal space along the left midclavicular line, over the anterior chest near the sternum. The material you’re studying groups these two together as the leads associated with the sternum, so this pair fits that description best. The other pairs involve leads that are either on the right side or further lateral from the sternum, so they aren’t described together with the sternum in the same way.
