Lead V3 is located between which two leads?

Explanation:
Lead V3 sits midway between the positions of V2 and V4 on the chest. In the standard 12-lead setup, V2 is placed at the left sternal border in the 4th intercostal space and V4 is at the left midclavicular line in the 5th intercostal space, so V3 is placed halfway between them to view the anterior heart between those sites. This is why the correct description is that V3 lies between V2 and V4. The other options place the lead relative to spots that don’t align with the chest-lead sequence.
