What characteristic defines the placement of the chest lead V1?

• A. It is positioned on the left side of the sternum
• B. It is positioned near the right shoulder
• C. It is positioned on the right side of the sternum
• D. It is positioned at the center of the chest

Answer: (C)

The placement of chest lead V1 is specifically located on the right side of the sternum, typically in the fourth intercostal space. This position allows for optimal viewing of the electrical activity of the heart, particularly the right ventricle and the septum, providing crucial information for diagnosing various cardiac conditions.

This placement is integral because it gives important insights into the electrical conduction through the heart's ventricles. Correct placement is essential for accurate EKG interpretation, as it ensures that the electrical impulses originating from the heart are captured correctly. Understanding the correct positioning of lead V1 is fundamental for any healthcare professional interpreting EKGs, as it influences the overall analysis and diagnosis of heart function.
