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.

iRhythm Technologies competitors and assessment
Company assessmentBroad 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.
