What is an EKG artifact?

An EKG artifact refers specifically to unwanted interference that can distort the EKG waveforms. This interference can arise from a variety of sources, including electrical devices nearby, muscle tremors, or poor electrode placement. When artifacts are present on an EKG, they can obscure the actual electrical signals generated by the heart, leading to misinterpretation and potential misdiagnosis. It is crucial for healthcare professionals to recognize and differentiate these artifacts from true cardiac events to ensure accurate readings and appropriate patient care. Understanding the nature of artifacts aids technicians in maintaining the integrity of EKG readings and making informed decisions based on the data they collect.
