ECG leads are electrodes placed on the skin that detect the electrical signals produced by the heart. These signals are then amplified and recorded by the ECG machine, which creates a visual representation of the heart's electrical activity on a graph.
The names of the ECG leads used to monitor heart activity are the standard limb leads (I, II, III, aVR, aVL, aVF) and the precordial leads (V1, V2, V3, V4, V5, V6).

Atrial depolarization in an ECG cycle is primarily represented by the P wave. This wave indicates the electrical activity that triggers the contraction of the atria. Leads II, III, and aVF are commonly used to visualize this process, but the P wave can be seen in all standard leads.

Lateral leads in a 12-lead ECG refer to the leads that primarily assess the electrical activity of the lateral wall of the left ventricle. These leads include I, aVL, V5, and V6. They provide important information about the heart's function and can help identify issues such as ischemia or infarction in the lateral region. Analyzing these leads is crucial for diagnosing various cardiac conditions.
When placing ECG leads on a patient with an amputation, it is essential to position the leads on the remaining limb or use alternative sites to ensure good electrode contact. For upper limb amputations, the leads can be placed on the torso or lower limbs, while for lower limb amputations, leads can be positioned on the arms or other accessible areas. It's important to ensure that the leads are placed symmetrically to maintain the integrity of the ECG readings. Additionally, using limb lead cables that are long enough to reach the alternative sites is crucial for accurate placement.

A standard electrocardiogram (ECG or EKG) typically uses 12 leads to record the heart's electrical activity. These leads include 10 physical electrodes placed on the body, which create 12 different views of the heart's activity. The 12 leads consist of 6 limb leads and 6 chest leads, providing comprehensive information for diagnosing heart conditions.
