Where is Lead V2 positioned in an ECG?

Lead V2 is positioned in the fourth intercostal space, just left of the sternum, which is the correct answer. This placement is significant because it allows for the effective monitoring of the anterior wall of the heart and captures electrical activity that may provide vital information about the heart's condition. V2, along with V1, plays an important role in examining the electrical axis, particularly in the context of the ventricles and their function.

Proper placement of the leads is crucial for accurate ECG readings, as it can influence the interpretation of cardiac rhythms and potential abnormalities. The fourth intercostal space is an established standard for V2 because it is directly related to the anatomical landmarks of the heart, ensuring that the lead picks up the correct electrical signals.
