Definitive diagnosis
Accelerated care

Flexible time frame
With up to 14 days of continuous ambulatory ECG monitoring, clinicians have all the data needed to make an accurate diagnosis from a single test.
Assured clinical accuracy
99% median analysable time combined with our deep neural network and review by highly trained cardiac technicians helps ensure critical insights aren’t missed.
Patient-friendly design
With no maintenance or special attention required, the Zio service facilitates high patient compliance.
We’re a digital healthcare company redefining the way cardiac arrhythmias are clinically diagnosed
Our Zio service allows physicians to diagnose many arrhythmias more quickly and efficiently than traditional technologies and avoid multiple indeterminate tests.

Arrhythmias have a £2.2b financial impact on healthcare systems
The current problem
Atrial fibrillation (AF) affects an estimated 1.4 million people in the UK, contributing to increased stroke risk and creating significant financial impact on healthcare systems. We believe that the Zio service allows physicians to diagnose many arrhythmias more quickly and efficiently than traditional technologies and avoid multiple indeterminate tests.
Early detection of heart rhythm disorders, such as atrial fibrillation (“AF”) and other clinically relevant arrhythmias, allows for appropriate medical intervention and helps avoid more serious downstream medical events, including stroke.

Over 3 million patients tested
Continuous, uninterrupted monitoring


Artificial intelligence (AI) and our Zio deep learning algorithm
Developed in collaboration with the Stanford Machine Learning Group, our deep neural network can detect and identify 10 arrhythmia classes. Combining deep learning and classic machine learning capabilities with our expert cardiac technician review, Zio by iRhythm gives physicians and patients the assurance of expert-level accuracy in arrhythmia detection.
