The pervasive technology of cardiac monitoring has greatly advanced patient care for several decades. Since its advent, telemetry has been used in a variety of settings to guide medical management in patients who are either acutely or non-acutely ill. Evidence from several studies supports the benefits of the 2004 American Heart Association (AHA) telemetry guidelines in stratifying patients into 3 groups based on their individual cardiac event risk. It has been shown to reduce hospital costs without compromising patient care as well as eliminate overflow of telemetry units. This article reviews the AHA cardiac telemetry guidelines and evaluates the current status of its implementation, the general benefits, as well as its limitations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
