Where should the AVF lead be placed during an EKG?

The placement of the AVF lead during an EKG is crucial for obtaining accurate readings of the heart's electrical activity. The AVF lead, which stands for Augmented Vector Foot, is specifically designed to provide information about the heart's electrical activity in the frontal plane. It is placed at the left foot, which acts as the positive electrode for this lead.

This positioning allows for the measurement of the voltage difference between the left leg and the other limbs, enabling the EKG to capture the electrical impulses as they travel through the heart. By using the left leg as the reference point, the AVF lead helps to assess how the heart's electrical signals are oriented towards the foot, contributing to a comprehensive view of the heart's function.

In this context, placing the AVF lead correctly at the left foot ensures that the readings obtained are accurate and reliable, aiding in the diagnosis of any potential cardiac issues.
