iRhythm is a digital healthcare company that develops and commercializes wire-free, patch-based wearable biosensors combined with proprietary cloud-based analytics software to help physicians detect cardiac arrhythmias and other cardiac conditions. The company operates as an independent diagnostic testing facility offering ambulatory cardiac monitoring services in multiple modalities, processing patient data through FDA-cleared analytics software to generate diagnostic reports and, in some cases, real-time clinical alerts delivered via integrated web-based and mobile platforms. iRhythm generates revenue by billing third-party payors—commercial insurers and government programs—for diagnostic services delivered to patients suspected of having difficult-to-detect arrhythmias, and is pursuing growth through deeper market penetration, evidence-based expansion into higher-risk populations, selective international expansion, and platform extension into adjacent cardiac and respiratory disease areas.
