Which lead position is typically placed at the 4th intercostal space at the right sternal border?

• A. V5
• B. V2
• C. V4
• D. V1

Answer: (D)

The lead position commonly placed at the 4th intercostal space at the right sternal border is V1. This lead is crucial in electrocardiography (ECG or EKG) as it helps visualize the electrical activity of the heart, particularly the right ventricle and the interventricular septum. By positioning V1 in this location, it provides valuable insights into arrhythmias and other cardiac issues. V1 is typically characterized by its positive deflections seen in the QRS complexes due to its anatomical placement. This lead is essential in diagnosing conditions such as bundle branch blocks and other conduction abnormalities. Accurate placement of V1 enhances the effectiveness of monitoring and diagnosing cardiac health, making it a vital component of a comprehensive ECG examination.
