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).

The unipolar limb leads (aVR, aVL, aVF) are three of the standard leads used in an electrocardiogram (ECG) to record electrical activity of the heart from different angles. They provide information on the heart's electrical activity in the frontal plane of the body.

applying leads for ECG cardiopulmonary resuscitation listening to heart sounds
CPT Code 93000 -Electrocardiogram, routine ECG with at least 12 leads; with interpretation and report.
Electrodes are placed on specific areas of the chest, arms, and legs for an ECG test.
A 3-lead ECG records electrical activity from three points on the body, while a 12-lead ECG records from 12 points. The 12-lead ECG provides a more comprehensive view of the heart's electrical activity, allowing for better detection of abnormalities. This increased number of leads improves the accuracy of cardiac monitoring by providing more detailed information about the heart's function and potential issues.
