Communication, Teach-Back and Diverse Patient Needs

Scope of Practice, Patient Identification, and Teach-Back Fundamentals

The EKG technician plays an essential clinical role focused on patient preparation, proper lead placement, and recording high-quality tracings. In addition to technical execution, the technician is responsible for recognizing artifacts and immediately notifying the licensed provider of life-threatening cardiac rhythms. However, clinical diagnosis and the formal interpretation of the EKG tracing fall strictly within the scope of practice of the licensed provider. When patients inevitably ask questions regarding their EKG results, what the waves mean, or what their diagnosis is, the technician must direct all such inquiries to the ordering physician or provider.

Establishing safety begins before touching any equipment. Patient identity must always be verified using at least two unique identifiers, typically the patient's full name and date of birth, prior to starting the procedure. Once identification is verified, the technician must explain the EKG procedure in clear, non-technical language to relieve patient anxiety. Technicians should inform the patient that an EKG is a painless, non-invasive test that records electrical signals from the heart. Patients are frequently worried about receiving a shock; reassuring them that the EKG machine only records signals and does not transmit electricity into the body helps establish trust. Before preparing the skin or applying electrodes, the technician must explain the steps and obtain the patient's consent in accordance with facility policy. Patients hold the right to refuse an EKG at any point. If a patient refuses, the technician must document the refusal and immediately notify the provider.

To ensure a clean diagnostic recording, the patient must be instructed to lie still, breathe normally, and avoid talking during the EKG recording. Simply asking 'Do you understand?' is rarely sufficient to verify patient cooperation. Instead, the technician should use the teach-back method, which requires asking the patient to explain instructions in their own words to confirm comprehension. Asking open-ended questions is an effective way to evaluate patient understanding during this process. For example, instead of asking if the patient knows what to do, the technician might ask, 'What are the three things you will need to do while the machine is actively running?' Hearing the patient repeat the guidance confirms they are prepared for the test.
