Where is the V5 electrode placed for a 12 lead ECG?

The V5 electrode is placed in the fifth intercostal space, between the V4 and V6 positions. This placement is significant because it allows for optimal visualization of the left lateral wall of the heart, which is important for detecting various cardiac conditions.

The fifth intercostal space is located roughly at the same vertical level as the apex of the heart, ensuring that the readings captured by this electrode provide valuable insights into the electrical activity of the left ventricle. By positioning V5 between V4 and V6, the placement is standardized, facilitating consistent and accurate interpretation of the ECG across different patients and settings.

This electrode's location directly contributes to the comprehensive understanding of the heart's electrical activity, which is crucial for effective diagnosis and management of potential cardiac issues.
