Certified Rhythm Analysis Technician (CRAT) Practice Exam 2026 - Free CRAT Practice Questions and Study Guide

The operation of a telemetry monitor is most commonly carried out by a nurse. Nurses are trained to monitor patients' vital signs and cardiac rhythms through telemetry systems, which allow for continuous observation of the heart's electrical activity. In a clinical setting, nurses assess the telemetry data, respond to alarms, and communicate changes in patient conditions to the medical team. Their training includes interpreting the data provided by the telemetry monitor, making them integral to patient care in settings such as hospitals.

While physicians and cardiologists are involved in diagnosing and treating heart conditions, they typically rely on the data provided by nurses and technicians rather than operating the equipment themselves. Technicians may assist in setting up or maintaining the telemetry systems, but the primary responsibility for monitoring and interpreting the data falls to the nursing staff. This division of responsibilities ensures a comprehensive approach to patient monitoring and care.
