What can cause artifact in telemetry readings?

• A. High humidity
• B. Muscle movement or interference from electronic devices
• C. Changes in atmospheric pressure
• D. Patient rest

Answer: (B)

Artifact in telemetry readings refers to any distortion or interference in the electrocardiogram (ECG) signals that can make the data unreliable or difficult to interpret. Muscle movement or interference from electronic devices is a primary cause of such artifacts. When patients move their muscles, especially during activities such as walking or adjusting their position, it generates electrical signals that can be picked up by the telemetry monitor. These signals can mask or mimic the electrical activity of the heart, leading to inaccuracies in the monitoring data. Similarly, nearby electronic devices, including cell phones, electrical equipment, or even poorly shielded telemetry leads, can introduce noise into the system, further complicating the interpretation of the heart's rhythm. Understanding the sources of artifacts is crucial for telemetry monitor technicians, as it allows them to minimize interference and ensure more accurate heart monitoring. By identifying and mitigating these factors, technicians can improve the quality of telemetry data and thus enhance patient care.
