What is another term used to refer to chest leads in an ECG?

The term "precordial leads" is commonly used to refer to the chest leads in an electrocardiogram (ECG). These leads are placed on the chest and are specifically designed to provide a view of the heart's electrical activity from the anterior and lateral perspectives. Precordial leads are essential for diagnosing various cardiac conditions as they allow for more localized readings of the heart's function compared to limb leads.

In contrast, thoracic leads might suggest a broader scope that could include additional thoracic monitoring, while peripheral leads typically refer to limb leads placed on the arms and legs, which capture different aspects of the heart's electrical activity. Central leads is not a standard term used in this context and does not accurately describe the role or placement of leads used in ECG recordings. Therefore, "precordial leads" is the most accurate terminology to describe the specific leads placed on the chest for ECG monitoring.
