Where is Lead V6 positioned during an ECG?

Lead V6 is positioned at the midaxillary line at the same horizontal level as Lead V4. This placement is important in a 12-lead ECG because it helps to capture the electrical activity of the heart from a lateral perspective, providing critical information regarding the left lateral wall of the left ventricle. The midaxillary line is an imaginary vertical line running down the side of the body and is crucial for ensuring that the lead placement accurately reflects cardiac electrical activity.

The specific location within the horizontal plane is aligned with V4, which is located at the fifth intercostal space at the midclavicular line. By placing V6 at the same horizontal level but at the midaxillary line, healthcare providers can gather comprehensive insights into the heart’s electrical function, particularly in evaluating potential conditions affecting the lateral wall of the heart, such as ischemia or infarction in that area.
