Where is the chest electrode V2 located?

The correct location of the chest electrode V2 is at the 4th intercostal space at the left margin of the sternum. This positioning is crucial for accurate EKG readings, as V2 provides important information about the heart's electrical activity, particularly from the left ventricle and the interventricular septum.

Placing V2 in the 4th intercostal space allows for optimal visualization of the heart's anterior and lateral walls, aiding in the detection of abnormalities such as ischemia or infarction. Proper placement is essential for ensuring that the EKG reflects an accurate representation of the heart's electrical activity, which can significantly impact diagnosis and treatment decisions.

Understanding the anatomy of the thoracic cavity and the intercostal spaces is vital for those in the medical field, as it helps ensure that electrodes are placed correctly for effective monitoring and diagnosis.
