To ensure accuracy before finalizing an EKG, checking the machine for artifacts is essential. Artifacts can be caused by a variety of factors, including patient movement, poor electrode contact, or external electrical interference. By inspecting the EKG for these artifacts, the technician can identify any irregularities that might compromise the quality of the recording. Ensuring that the tracing is clear and devoid of artifacts is critical for an accurate interpretation of the heart's electrical activity.

While ensuring patient comfort, disconnecting the patient immediately, or re-applying all electrodes can play roles in the overall EKG process, they don't specifically address the immediate need to confirm the reliability of the EKG readout prior to finalization. Ensuring there are no artifacts is a key step that directly impacts the accuracy of the EKG results and helps to avoid misdiagnoses or missed conditions.
