-Gillian is a cheerful, active teenager who is having an ECG as part of a physical required by her school to participate in cheerleading activities. You explain that she needs to remain very still while you record the ECG. You begin the tracing, as shown in the picture. Although Gillian remains still, when she sees the look on your face, she asks, "What's wrong?" What abnormality is visible in lead V6, and what is your best choice of action?

Accepted Answer

A)   Somatic interference; ask Gillian again to remain still
