What is another name for leads aVR, aVF, and aVL?

Leads aVR, aVF, and aVL are referred to as augmented leads because they utilize a technique that amplifies the electrical signals from the heart. In an electrocardiogram (ECG), these leads are specific types of unipolar leads, which means they measure the electrical potential at one electrode relative to a virtual reference point created by the other electrodes. The term "augmented" highlights that the signals from these leads are increased in amplitude, allowing for better visualization of the heart's electrical activity.

This amplification is crucial for providing a clearer picture of the heart's electrical activity, particularly in the frontal plane. The augmented leads are designed to enhance the recording of electrical impulses that may be difficult to interpret using standard bipolar leads alone. Thus, the use of the term "augmented" is accurate as it reflects the methodology behind obtaining these specific leads on an ECG.
