About the Company

iRhythm Technologies

Wearable cardiac monitoring with data analysis

iRhythm Technologies develops cardiac monitoring technology, led by the Zio Patch wearable for up to 14 days of continuous heart-rhythm tracking. The patch is worn by a patient to collect long-term data, which is then analyzed by iRhythm’s services to provide diagnostic insights to healthcare providers without requiring frequent in-person visits. Compared with competitors, it combines extended, non-intrusive monitoring with integrated data analysis to streamline clinician workflows and support telehealth, selling both devices and analysis services to providers. The goal is to improve detection of arrhythmias, enhance diagnostic accuracy, and make patient care and clinician workflows more efficient through scalable wearable monitoring and interpretation of the collected data.
