What is the primary purpose of augmented leads?

The primary purpose of augmented leads in an electrocardiogram (ECG) is to enhance electrical signals from the heart, allowing for a clearer and more comprehensive view of the heart's electrical activity. Augmented leads, which include aVR, aVL, and aVF, are derived from the standard limb leads but adjust the voltage to provide a more detailed representation of the heart's electrical impulses from different angles.

By enhancing these signals, augmented leads help in capturing subtle changes in the heart's rhythm and electrical pathway, which can be critical for diagnosing various cardiac conditions. This enhancement is particularly useful in clinical settings, as it aids healthcare providers in making informed decisions regarding patient care and treatment. The ability of augmented leads to provide additional information complements the standard leads and contributes to a more accurate overall assessment of the heart's health.
