What problem is present and how can you fix it?

B) Somatic interference; ask the patient to be very still while you record the ECG
C) Wandering baseline; check and reconnect loose leads
D) Flat line; check for crossed wires or loose leads
E) AC interference; move the ECG equipment to a room farther from other electric equipment
