iRhythm Technologies, Inc. IRTC has received FDA 510(k) clearance for design changes and enhancements previously made to its Zio AT device. These modifications, submitted via letter to file, ensure the device remains available for shipment within the United States. The clearance follows the first of two submissions made this year, which are part of iRhythm's ongoing efforts to maintain regulatory compliance and service quality.

The Zio AT device is designed for long-term ECG monitoring, capturing both symptomatic and asymptomatic cardiac events in patients aged 18 or older. It helps detect transient symptoms such as palpitations, dizziness, shortness of breath and fatigue. However, it is not intended for use in critical care patients.

The Zio AT device is a prescription-only mobile cardiac telemetry (MCT) system for outpatient cardiac monitoring. It includes the Zio AT patch, which records ECG data for up to 14 days, and a wireless gateway that transmits data to iRhythm's Zio ECG Utilization Software (ZEUS) for analysis using deep-learning algorithms. During the wear period, event transmission reports are generated, followed by a comprehensive final report for physicians to make clinical decisions. The Zio AT services are provided through iRhythm's diagnostic testing facilities in San Francisco, Deerfield and Houston.
