What is the correct placement for V6 in a 12-Lead ECG?

The correct placement for V6 in a 12-lead ECG is on the midaxillary line, level with V5. This location is important because V6 is one of the chest leads that helps to provide information about the heart's activity in the horizontal plane, particularly in the lateral wall of the left ventricle.

When placing V6, it is positioned along the midaxillary line, which runs vertically down the body at the midpoint of the armpit (axillary region). By placing V6 at the same horizontal level as V5, which is located at the left fifth intercostal space near the sternum, it ensures an accurate representation of the heart's electrical activity from this perspective. This standardization is crucial for the interpretation of the ECG, as it allows for consistent comparisons between different recordings.

The other placement options do not align with standard ECG lead placement guidelines, which is why they are not suitable for correct V6 placement. Following these guidelines is essential for obtaining an accurate and reliable ECG that reflects the patient's cardiac status.
