ECG leads explained | Limb leads & Chest leads | easy and simple

Описание: In this video, we will understand ECG leads in a simple and logical way so that you don’t have to memorize blindly. A standard 12-lead ECG uses 10 electrodes to record the electrical activity of the heart from different angles. These include 4 limb electrodes placed on the right arm, left arm, right leg (ground electrode), and left leg, which together form 6 limb leads—3 bipolar leads (Lead I, II, III) and 3 augmented leads (aVR, aVL, aVF). In addition to this, there are 6 chest (precordial) leads from V1 to V6, placed at specific anatomical landmarks on the chest, each giving valuable information about different regions of the heart.
V1 and V2 mainly look at the septal region, V3 and V4 view the anterior wall, while V5 and V6 represent the lateral wall of the heart. Correct placement of these leads is extremely important for accurate ECG interpretation, as even small errors can change the ECG pattern. This video will help students and clinicians clearly understand lead placement, electrode positioning, and the clinical significance of each ECG lead, making ECG interpretation easier and more confident.
