The Cardiac Telemetry Technician (CTT) works under the supervision and direction of a registered nurse. The CTT observes electrocardiogram (ECG) tracings on monitored patients, reports rhythm changes and arrhythmias to the registered nurse caring for the patient, activates Rapid Response Team (RRT) and/or the physician if needed, documents rhythms and arrhythmias, and records rhythm strips and other data per policy.
