Question: 1 / 975

On a 12-lead ECG, which leads are classified as anterior leads?

V1 and V2

V3 and V4

The anterior leads on a 12-lead ECG are indeed V3 and V4. These leads are positioned on the anterior wall of the left ventricle and specifically are located over the left precordial area.

In the context of the ECG, anterior leads are crucial for assessing the electrical activity of the anterior part of the heart. When interpreting an ECG, recognizing these leads is essential for identifying conditions such as anterior wall myocardial infarctions, which can provide critical information about a patient’s cardiac status.

The placement of these leads provides a focused view of the anterior wall, which makes them vital in diagnosing various cardiac issues. Understanding the location and function of each lead on the ECG can significantly impact the interpretation and subsequent management of cardiac conditions.
