In a standard telemetry setup, where are the precordial leads placed?

• A. Precordial leads V1-V6 in standard positions; limb leads placed on shoulders/trunk to approximate limb lead placement
• B. Precordial leads V1-V6 on the abdomen
• C. Only limb leads used
• D. V1-V6 on the chest but without limb leads

Answer: (A)

In telemetry, the six precordial leads are placed on the chest in their standard V1 through V6 positions, while the limb leads are placed on the shoulders or trunk to approximate the limb-lead placement when the arms and legs aren’t accessible. This arrangement preserves the chest-wall views these leads provide and keeps the overall limb-lead vectors in line with normal ECG interpretation. Placing V1–V6 on the abdomen would not give the correct chest views, using only limb leads misses the chest information, and putting V1–V6 on the chest without any limb leads would not yield a complete 12-lead view.
