Streamlined cardiac monitoring made simple

Our goal is to help simplify the cardiac monitoring experience end to end. The iRhythm monitoring service helps you accomplish your program goals by delivering clinical accuracy while reducing the cost of care.2-6

  • 2x more likely to result in specified arrhythmia diagnoses compared to Holter monitoring services3-6
  • 2.6x greater detection of atrial fibrillation vs. usual care5-7
  • 98% usable recording1,6,8
  • 99% patient compliance for continuous, uninterrupted ECG recording9
  • 81% of patients preferred wearing a Zio LTCM device for 
14 days over a 24-hour Holter monitor5,10
  • Minimal disruption1,11-13 to patients’ daily activities with no maintenance or battery changes required11-14
  • 99% physician agreement with the Zio® end-of-wear report15
  • Robust reports leveraging iRhythm's advanced service and deep-learned AI algorithm17-20
  • Convenient report access with ZioSuite® web portal and mobile app
  • LTCM services as a category was associated with the lowest incremental acute care utilization compared to other types of monitoring services3-6
  • Zio LTCM service had the lowest likelihood of repeat testing compared to all other monitoring services3-6

Proven precision

The value of the iRhythm monitoring service has been demonstrated in over 100 original scientific research manuscripts.20

Zio report

End-of-wear reports with 99% physician agreement15

The Zio® end-of-wear report is generated by an FDA-cleared, deep-learned algorithm that can detect 13 different types of arrhythmias, plus sinus rhythm and artifacts, and is curated and verified by Certified Cardiographic Technicians.16-19

  • The algorithm can classify a broad range of distinct arrhythmias with high diagnostic performance similar to that of cardiologists17
  • End-of-wear report provides a comprehensive analysis based on the full wear period16-19
  • The Zio report provides you with a rich summary of clinically actionable cardiac events on the first page — and an easy-to-navigate deep dive for all the intricate details captured
