Lead placement for a standard telemetry setup. Which statement is accurate?

• A. Limb leads placed on shoulders/trunk to approximate limb lead placement
• B. Precordial leads V1-V6 in standard positions
• C. Lead placement uses only limb leads
• D. Precordial leads V1-V4 and V5-V6

Answer: (B)

In a standard telemetry setup, the six chest (precordial) leads are placed on the chest in their conventional anatomical positions to give a consistent, multi-angle view of the heart’s electrical activity. These V leads run from V1 at the right sternal border to V6 at the left midaxillary line, creating a front-to-side view that aligns with how the heart is oriented within the chest. This precise, standard placement is what makes the tracing interpretable and comparable to the standard ECG framework, so stating that the precordial leads V1 through V6 are in their standard positions is the most accurate description. Limb leads aren’t placed on shoulders or trunk in the standard setup—they’re placed on the limbs (arms and legs). The system isn’t limited to limb leads only, and a description that omits the standard chest-lead positions or uses a nonstandard phrasing can be misleading.
