Where is V4 located on the chest?

V4 is an important lead in the electrocardiogram (ECG) that provides valuable information about the heart's electrical activity, specifically from the anterior view of the heart. The correct placement of V4 is situated at the left side of the chest in the 5th intercostal space, specifically at the midclavicular line.

This positioning allows for optimal electrical readings from the heart's apex. By placing V4 at the 5th intercostal space left side-clavicle line, it ensures that the lead accurately captures electrical signals emanating from the left ventricle.

This anatomical understanding is crucial for correctly interpreting ECGs and diagnosing clinical conditions related to cardiac function. Proper lead placement is essential for obtaining reliable and meaningful data from the ECG, which could inform decisions regarding patient care and management.
