In which lead position would you place the white electrode in a standard 12-lead ECG setup?

• A. Left arm
• B. Right arm
• C. Left leg
• D. Right leg

Answer: (B)

In a standard 12-lead ECG setup, the white electrode is placed on the right arm. This positioning aligns with the established convention for electrode placement, where the coloring helps technicians easily remember the correct locations. Specifically, the electrodes have standardized colors: white for the right arm, black for the left arm, red for the left leg, and green for the right leg. Correct placement of the right arm for the white electrode is critical for accurate ECG readings, as it ensures proper electrical connectivity and signal acquisition from the heart. An incorrectly placed electrode can lead to poor-quality readings or misinterpretations of the heart's electrical activity. Understanding these conventions is essential for technicians in providing consistent and reliable patient care, as well as in ensuring that ECG tracings can be compared over time or among different patients effectively.
