What color represents the right leg lead in an ECG configuration?

• A. White
• B. Green
• C. Black
• D. Red

Answer: (B)

In an ECG configuration, the right leg lead is typically represented by the color green. This color coding is part of the standardized system used to ensure consistency and reduce the likelihood of errors during ECG placements. The green lead is placed on the right leg and serves as a ground reference in the lead system, contributing to the overall accuracy of the ECG readings.

Having a standardized color scheme simplifies the process for healthcare professionals when attaching the leads, enabling quick identification and connection. Each color is designated for a specific limb or chest position, allowing technicians and clinicians to quickly and accurately set up the ECG, which is essential for effective patient monitoring and diagnosis.
