ECG Technician Responsibilities and Scope of Practice
Domain 1 examines where the ECG technician's job ends and the clinician's begins, plus the legal, ethical, and safety duties that surround every tracing.
Core rules
- Perform ordered 12-lead ECGs, rhythm strips, Holter/event monitor hookups, and related tasks; obtain technically adequate tracings. Do not interpret rhythms, diagnose, or label a tracing as normal.
- Verify the order and two patient identifiers before starting. Explain the procedure, obtain the patient's permission, provide privacy, and follow HIPAA confidentiality.
- Use standard precautions: hand hygiene; gloves when contact with body fluids, non-intact skin, or soiled items is likely; clean reusable cables and lead wires per manufacturer and facility policy.
- Recognize immediately life-threatening findings-ventricular fibrillation, pulseless ventricular tachycardia, asystole, severe bradycardia, ST elevation-and escalate at once through the chain of command or emergency response system.
- Do not administer medication, defibrillate, pace, or adjust therapy unless you hold a separate license and are authorized by facility policy.
- Document objectively: what was done, when, what was observed, and whom you notified.
Worked example
A patient reports crushing chest pain during a 12-lead ECG. The tracing shows marked ST elevation in leads II, III, and aVF. The technician says the doctor will review this immediately, keeps the patient still, and calls the supervising nurse or physician now. The technician does not say the patient is having a heart attack and does not write an interpretation on the strip; the machine's automated statement is not a diagnosis.
Traps that cost marks
Giving a diagnosis or prognosis; discussing findings in a hallway; skipping identity verification because the room is busy; treating the computer interpretation as final; failing to document the notification time and the person notified.
