iRhythm Holdings develops wearable cardiac monitoring systems, led by the Zio patch, a long-wear adhesive ECG device that records heart rhythm continuously for days to weeks. Its cloud-based analytics and AI-assisted review help physicians detect arrhythmias such as atrial fibrillation with higher yield than short traditional Holter tests. The company primarily serves cardiology practices, health systems, and patients needing outpatient cardiac diagnostics.
