Clarity That Drives Confidence

iRhythm continually strives to perfect the cardiac monitoring experience. Our physician-prescribed Zio ECG monitors and end-to-end service are designed to capture heart rhythm information over an extended period, supporting clinicians to make informed care decisions

Here's how it works

Monitor Application

A Zio™ monitor is applied in-clinic as prescribed by the physician.

Monitoring Period

The patient wears the monitor for the duration recommended by the clinician, then returns it back to iRhythm.

Data Analyses

iRhythm analyses the data using its advanced AI Zio™ ECG Utilization Service (ZEUS) System and produces an end-of-wear report verified by Qualified ECG Specialists (QES).

Report Delivery

Physician receives an actionable report to support care decisions.
