The Role of Cardiac Telemetry Unit Nurses in the Surveillance of Cardiac Arrhythmias in Hospital Settings

Abstract

            Cardiac telemetry is a technology used for continuous monitoring of cardiac rhythms to detect abnormalities such as cardiac arrhythmias in a timely manner. This monitoring system is commonly implemented in large or university hospitals where cardiology specialists are available and nurses possess expertise in electrocardiogram (ECG) interpretation. The system also requires substantial financial investment in patient monitoring devices. In many institutions, nurses are assigned primary responsibility for continuously monitoring, analyzing, and interpreting ECG rhythms for 24 hours a day. Their role is essential in detecting potentially life-threatening abnormalities, enabling prompt medical management, reducing complications, and lowering mortality rates. Nurses responsible for cardiac telemetry monitoring must possess both basic and advanced competencies in ECG interpretation, as well as the ability to assess cardiac emergencies. Effective communication and coordination with interdisciplinary healthcare teams are also essential to ensure timely clinical responses. In addition, telemetry nurses provide guidance to ward nurses in managing arrhythmic events and educate patients and their families to enhance understanding and reduce anxiety during monitoring. Although the use of cardiac telemetry has increased in hospital settings, nursing roles in ECG surveillance vary across organizational contexts. Moreover, systematic synthesis of knowledge that clearly defines nursing roles, competencies, and scopes of practice in cardiac telemetry monitoring remains limited. Therefore, this article aims to present and synthesize current knowledge regarding cardiac telemetry systems and the roles of nurses in monitoring cardiac arrhythmias. The findings may support appropriate clinical application, enhance monitoring efficiency, and improve nursing outcomes for patients undergoing cardiac monitoring.
