V leads are synonymous with which category of ECG leads?

• A. Augmented leads
• B. Unipolar leads
• C. Chest/precordial leads
• D. Standard limb leads

Answer: (C)

V leads are the chest or precordial leads. They are placed on the chest wall in six positions (V1 through V6) to capture the heart’s electrical activity from the front in the horizontal plane. This grouping is defined by electrode location on the chest rather than limb placement, which is why they’re categorized as chest/precordial leads. Each position views different areas of the heart: V1–V2 focus on the septum, V3–V4 on the anterior wall, and V5–V6 on the lateral wall. Although these chest leads are unipolar in design, their defining feature is their chest placement, distinguishing them from standard and augmented limb leads.
