An ECG is performed on a patient by connecting leads to the patient's:

• A. Chest, arms and legs
• B. Head, arms and legs
• C. Head, neck and arms
• D. Feet, neck and arms

Answer: (A)

The correct approach to performing an electrocardiogram (ECG) involves connecting leads to the patient's chest, arms, and legs. This configuration allows for the recording of the heart's electrical activity from multiple angles, which is crucial for accurate assessment and diagnosis of cardiac conditions. By placing leads on the chest (also referred to as precordial leads) as well as the arms and legs (limb leads), the ECG captures electrical impulses as they travel through the heart. Specifically, the chest leads are positioned to give a view of the heart's vertical plane, while the limb leads provide a horizontal plane. This comprehensive coverage is essential for medical professionals to interpret the heart's rhythm, detect abnormalities, and make informed decisions regarding patient care. The other options incorrectly suggest combinations of body areas that do not adequately cover the necessary perspectives for ECG recording, thereby failing to facilitate a complete evaluation of cardiac activity.
