In what order are the chest leads placed on a patient's chest?

• A. From left to right, starting with V1
• B. From right to left, starting with V1
• C. From top to bottom, starting with V1
• D. From bottom to top, starting with V1

Answer: (B)

The placement of chest leads for an EKG is crucial for accurate interpretation, particularly in determining the electrical activity of the heart from different perspectives. The correct order of placement begins with V1, which is positioned at the right fourth intercostal space at the sternal border.

From V1, the subsequent leads are placed across the chest in a horizontal fashion, moving from right to left. This arrangement allows for a systematic and standardized viewing of the heart's electrical activity as you progress through leads V2, V3, V4, V5, and finally V6. The left-sided leads (V2 through V6) monitor the heart's lateral and posterior aspects, whereas V1 provides insight into the right ventricle and septum.

This configuration is essential for consistent and reproducible results in EKG readings, helping clinicians accurately diagnose heart conditions. This systematic approach distinguishes itself from alternative arrangements that might suggest vertical placements or reverse orders, which would not provide the necessary comprehensive view of the heart’s activity.
