What is the location for the placement of V2 lead?

The placement of the V2 lead in an electrocardiogram (ECG or EKG) is critical for accurately monitoring the electrical activity of the heart. The specific location for V2 is at the fourth intercostal space (ICS) at the left sternal border. This positioning allows for optimal viewing of the heart's anterior wall and provides valuable information regarding the heart's electrical signals.

By placing the V2 lead at this location, it captures the electrical activity traveling toward the lead, enhancing the representation of the heart's electrical activity in the anterior view. Accurate lead placements are vital for diagnosing various cardiac conditions, and the choice of placement reflects a standard protocol used in clinical practice.

The other locations provided do not align with the standard placement for V2, as they do not provide the same perspective on the heart's electrical activity necessary for effective analysis.
