Lead V1 is positioned at the right sternal border in the fourth intercostal space, making it uniquely suited to provide a view of the right atrium and right ventricle. This lead is particularly effective for detecting abnormalities in these two chambers due to its anatomical placement, which allows it to capture the electrical activity occurring within the right side of the heart. The orientation of Lead V1 helps visualize both atrial and ventricular depolarization.

In contrast, other leads such as Lead I, Lead II, and Lead aVF focus on different aspects and areas of the heart. Lead I primarily provides a view of the heart's lateral wall, while Lead II views the inferior portion of the heart, and Lead aVF also captures the inferior aspect but from a different angle. Thus, they are not as effective as Lead V1 in highlighting the electrical activity specifically associated with the right atrium and ventricle.
