Rationale 3: Factors that can negatively impact the quality of an ECG tracing include incorrect positioning of leads.
Rationale 4: If electrical equipment in the room, such as an IV pump, is not grounded, electrical interference can occur.
Rationale 5: Electrodes that are in firm contact with the skin ensure the accuracy of the test.
