Step-by-step simplicity

Physicians prescribe the iRhythm monitoring service, and the Zio® ECG ambulatory monitor is applied to the patient in clinic or at home.

Patient wears the monitor and then mails it back to iRhythm.*

iRhythm analyzes the data, leveraging a proprietary, deep-learned AI algorithm and a team of highly trained CCTs.

Physicians receive a high-quality, clinically actionable end-of-wear report.

*Zio AT® service also provides wear-time transmission reports and daily reports.

The impact of accuracy

The end-to-end iRhythm monitoring service creates a better experience for you and your patients and helps you achieve your program goals.5-10

Zio long-term continuous monitoring (LTCM) improved clinical outcomes

  • 2x more likely to result in specified arrhythmia diagnoses compared to Holter monitoring services6-9
  • 72% more likely to result in specified arrhythmia diagnoses compared to event monitoring services6-9
  • 2.6x greater detection of atrial fibrillation vs. usual care8,9,11

LTCM reduced cost of care

  • Zio LTCM service was associated with the lowest average ED and inpatient hospital utilization compared to event and Holter monitoring services6-9
  • Lowest likelihood of retest among continuous cardiac monitoring services6,8,12

Higher patient satisfaction

  • 81% of patients preferred wearing a Zio LTCM monitor over a Holter8,13
  • 91% of patients wearing Zio monitor report it is easy to use and 90% would wear again14

Monitors that deliver the power of precision

Zio ECG monitors are specifically designed to fit patients’ daily lives, leading to astounding patient compliance.15,16 They offer high-quality, accurate data you can trust and help lead to the right diagnosis the first time.17
