Where is Lead V6 placed?

Where is Lead V6 placed?

• A. 4th intercostal space at the left anterior axillary line
• B. 5th intercostal space at the left midaxillary line
• C. 6th intercostal space at the left anterior axillary line
• D. 5th intercostal space at the right midclavicular line

Answer: (B)

Lead V6 is placed on the left chest at the level of the 5th intercostal space along the midaxillary line. This positioning gives a view of the heart’s electrical activity from the lateral left side and sits in line with leads V4 and V5, creating a consistent horizontal row across the chest. The landmarks—5th intercostal space between the ribs, and the midaxillary line down the side of the body—help ensure the electrode rests over the left lateral chest wall where the heart’s electrical signals are best captured from that angle. Placing it elsewhere (higher or on the opposite side) would alter the view and make comparisons less reliable.
