An assembly of devices designed to continuously measure and wirelessly transmit electrocardiographic (ECG) signals from a patient to a receiving location (e.g., central station, bedside monitor) for viewing. It typically consists of a portable transmitter with antenna and attached sensors (e.g., leads and electrodes) that are connected to the patient, as well as a receiver typically incorporated into a central station or bedside monitor that receives, consolidates, and displays the information. The system is typically used for ambulatory patients who require continuous monitoring (e.g., patients in step-down care areas).
