Overview

AliveCor is a U.S. medical technology company focused on electrocardiogram (ECG/EKG) acquisition, analysis, and remote cardiac rhythm monitoring. It combines portable sensors, mobile applications, and software algorithms to let users record single-lead ECGs outside a hospital and use the results for personal health management, clinician communication, or clinical monitoring. Its products are generally designed to work with smartphones or wearable devices, with the Kardia family forming a central part of the brand's product portfolio. Rather than concentrating on large hospital-based ECG systems, AliveCor focuses on more deployable tools for consumers, healthcare professionals, and telehealth settings. The company is privately held, and reliable public information on revenue, unit sales, and valuation is limited. Product indications, regulatory clearances, features, and market availability can vary by jurisdiction.

History

AliveCor was founded in 2011 with the aim of extending ECG recording beyond hospitals and clinics into mobile and everyday-use settings. It subsequently built a product system around portable sensors, smartphone applications, and automated rhythm analysis, releasing ECG devices and services under the Kardia brand for consumers and healthcare professionals. Its product approach reflects the broader shift in digital health from standalone hardware toward integrated device-and-software services: a user records an ECG, the application displays and analyzes the data, and the result can be incorporated into communication with clinicians or remote-care workflows. The company also explored integrating ECG capability into wearable devices, including the KardiaBand product for Apple Watch. Because AliveCor is privately held, public information about its internal operations, sales scale, and future product plans is limited. Regulatory clearances in each country also affect the features and permitted uses of its products.
