What color is associated with the V4 lead in ECG lead placement?

The V4 lead in ECG lead placement is associated with the color blue. Understanding the color coding in ECG lead placement is important for accurately connecting leads to a patient's chest, which ensures proper cardiac monitoring. The standard practice utilizes specific colors for each lead to maintain consistency and reduce the chance of errors during setup.

V4 is positioned at the left fifth intercostal space, at the midclavicular line. Its placement is essential for assessing the heart's electrical function, particularly in the left anterior descending artery territories. Therefore, recognizing that blue corresponds with V4 helps medical professionals quickly identify and place the ECG leads appropriately while also facilitating communication among healthcare team members.
