What is the correct placement for Lead V5?

The correct placement for Lead V5 is at the fifth intercostal space, midway between Lead V4 and Lead V6. This location is crucial for accurately capturing the electrical activity of the heart, especially from the left lateral wall.

Since Lead V4 is placed at the fifth intercostal space in the left midclavicular line and Lead V6 is positioned at the same intercostal space in the left midaxillary line, placing V5 midway between these two leads ensures it effectively monitors the heart's lateral wall. Proper placement is essential for diagnostic accuracy in electrocardiograms, as slight deviations in lead positioning can affect the readings and ultimately influence clinical decisions.

Other placements provided in the options do not correspond to the standard convention for V5, as they either misplace the lead in relation to the anatomical landmarks or describe locations intended for different leads.
