Revenue model

1. Zio Monitor Services: iRhythm provides ambulatory cardiac monitoring services through its Zio platform. Revenue is generated through billing for technical component (CPT 93243/93247 for Zio monitor) and interpretation services. The company bills insurance for the technical component while physicians bill for interpretation.
2. Zio AT Mobile Cardiac Telemetry: Mobile cardiac telemetry services billed under CPT code 93229 (technical component) and 93228 (interpretation). Provides continuous recording with wear-time transmissions and comprehensive end-of-wear reports.

Core offering

iRhythm Technologies provides ambulatory cardiac monitoring services through its Zio platform, combining single-use wearable ECG biosensors (Zio monitor and Zio AT) with an FDA-cleared deep-learned AI algorithm (ZEUS) and Qualified Cardiac Technician review. The service delivers continuous cardiac rhythm recording for up to 14 days, AI-assisted arrhythmia detection across 13 arrhythmia classes, and physician-ready end-of-wear reports with 99% physician agreement, distributed via the ZioSuite clinician portal, MyZio patient app, and integrated EHR workflows.

Product overview

iRhythm Technologies offers a unified cardiac monitoring platform centered on its Zio brand of ECG monitoring products and services. The core portfolio consists of the Zio monitor (long-term continuous monitoring up to 14 days) and Zio AT (mobile cardiac telemetry with real-time transmissions), both single-use wearable ECG patches. These devices are supported by the ZioSuite clinician portal (web and mobile app for patient management and report interpretation), the MyZio patient app (for symptom logging and patient support), and EHR integration services connecting with Epic, Cerner, Athena, Meditech, eClinicalWorks, and 450+ other systems via HL7 and Epic Aura network. The platform's intelligence is powered by the FDA-cleared ZEUS deep-learned AI algorithm, which analyzes continuous ECG data to detect 13 arrhythmia types with cardiologist-level accuracy, verified by Qualified Cardiac Technicians to generate physician-ready reports with 99% physician agreement. The service also includes Home Enrollment capabilities for at-home monitor application and the iRhythm Academy education platform for healthcare professionals.

Partnerships

Four partnerships are on record, tiered core.

• Heartbeat HealthcoreStrategic or Co-development PartnerPartnership where Heartbeat Health's virtual cardiology practice provides comprehensive diagnostics and care planning alongside iRhythm's cardiac monitoring solutions. The partnership enables enhanced arrhythmia detection to virtual cardiology expertise, empowering care teams to enhance outcomes, streamline workflows, and drive results.
• Lucem HealthcoreStrategic or Co-development PartnerPartnership announced July 2025 to introduce a predictive AI solution for early detection of arrhythmias in patient populations with comorbid conditions. Combines iRhythm's cardiac monitoring with Lucem Health's predictive analytics capabilities.
• Senko Medical (泉工医科工業)coreChannel Partner/ Reseller/ DistributorSenko Medical representatives distribute iRhythm's Zio ambulatory ECG monitoring services in Japan. The partnership enabled the May 2025 launch of Zio Long-Term Continuous Monitoring Service in Japan with PMDA-approved deep-learning AI.
• Epic (via Aura Network)coreTechnology or IntegrationiRhythm is the first medical device company to offer services through Epic's Aura network, enabling seamless and secure transmission of Zio orders and results. Provides one-time seamless setup with prebuilt orders and questions.

Expansion highlights6 records

Broad incumbents

• GE Healthcare (incl. MUSE and patient monitoring): GE Healthcare is a broad incumbent in cardiology diagnostics (ECG carts, MUSE cardiology information systems, hospital patient monitoring). Competes with iRhythm indirectly at the health system level through integrated diagnostic suites rather than as a focused ambulatory patch specialist.
• Hillrom / Baxter (now part of Baxter): Baxter (which acquired Hillrom) offers hospital-based cardiac monitoring, ECG carts, and connected care platforms. Competes with iRhythm at the inpatient and ambulatory boundary, particularly for telemetry and continuous monitoring workflows in hospitals.
• Medtronic (Cardiac Diagnostics): Medtronic's cardiac diagnostics portfolio includes LINQ insertable cardiac monitors (ICM) and remote monitoring services, competing indirectly with Zio in long-term arrhythmia detection while offering broader cardiac rhythm management including pacemakers and ICDs.
• Abbott (Cardiac Diagnostics): Abbott's cardiovascular franchise includes the Confirm Rx insertable cardiac monitor and CardiioMEMS heart failure diagnostics. Competes with iRhythm in long-duration cardiac monitoring, particularly for patients with infrequent or hard-to-capture arrhythmias.

Emerging players

• Eko Health: Eko Health combines digital stethoscopes with AI algorithms for cardiac and pulmonary disease detection. Overlaps with iRhythm in AI-driven cardiac diagnostics and primary care screening use cases, though Eko focuses on point-of-care rather than long-duration patch monitoring.
• Huxley Medical: Huxley Medical is an early-stage company developing AI-enabled wearable cardiac monitoring devices aimed at ambulatory arrhythmia detection. Directly comparable to iRhythm's patch-based LTCM service with potential overlap in cardiology and primary care channels.

Direct peers

• AliveCor: AliveCor makes KardiaMobile, a consumer and clinical single-lead ECG device with AI-based AFib detection, overlapping with iRhythm's short-duration and at-home screening use cases. Targets primary care, cardiology, and health plan channels similar to iRhythm's emerging GTM.
• Boston Scientific (Preventice Solutions): Boston Scientific owns Preventice Solutions (BodyGuardian), a wearable cardiac monitoring service offering MCT, event, and Holter patches. Direct competitor in ambulatory ECG services with overlap in Zio AT's mobile cardiac telemetry category.
• Philips (BioTelemetry): Philips acquired BioTelemetry, a leading provider of ambulatory cardiac monitoring services (event, Holter, MCT). Direct competitor to iRhythm's Zio service in the same hospital, cardiology practice, and IDN customer base using similar CPT-coded reimbursement pathways.

Regional players

• HeartFlow: HeartFlow offers AI-driven coronary CT-derived FFR analysis for cardiovascular disease diagnosis, complementary to but not directly competing with iRhythm's arrhythmia monitoring. Shares the same cardiology customer base and AI-enabled cardiac diagnostics positioning.
