iRhythm Holdings, Inc. IRTC

IRTC Company Overview

iRhythm Technologies, Inc. (NASDAQ: IRTC) is a digital healthcare company focused on cardiac monitoring and arrhythmia diagnostics. The company operates primarily within the ambulatory cardiac monitoring, digital health, and medical device industries. Its core offering is the Zio platform, a long-term continuous cardiac monitoring system that combines wearable biosensor technology, cloud-based data processing, and proprietary analytics to assist physicians in detecting cardiac arrhythmias. Revenue is generated primarily through diagnostic monitoring services tied to the use of the company’s wearable patches and associated clinical reporting services reimbursed through healthcare payors.

The company serves hospitals, physician practices, health systems, and ambulatory care providers, with a strong concentration in the U.S. healthcare market. iRhythm positions itself as an integrated cardiac diagnostics provider rather than solely a hardware manufacturer, differentiating itself through extended monitoring duration, data analytics capabilities, and workflow integration for clinicians. Founded in 2006, the company developed its early technology around adhesive wearable biosensors designed to replace traditional Holter monitors. Over time, it expanded from hardware development into AI-assisted diagnostic reporting and digital cardiac care infrastructure.
