Zio™ is more than a device: it’s an experience. In the cardiac ambulatory monitoring space, it combines novel, patient-centric devices coupled with world-class service from the highly trained staff at the iRhythm National Clinical Center (iNCC).

The development of the Zioâ„¢ platform is based on enhancing the overall experience for everyone involved in the monitoring process from start to finish. For physicians, the Zioâ„¢ aids in patient diagnosis by combining a simple, sophisticated device with a clear report format. For clinical staff, we offer a hygienic, new device for each patient, and a knowledgeable, responsive service team providing 24 hour, 7 day/week support to help clinical staff members care for their patients. For patients, the devices offer the most inconspicuous, easy-to-wear monitors available, designed to enhance compliance and simplify the monitoring experience, while maximizing diagnostic yields.
