CardioNet

CardioNet, founded in 1994 by serial entrepreneur James M. Sweeney, pioneered real-time, ambulatory cardiac monitoring. Sweeney, known for founding the home infusion therapy industry with Caremark, envisioned a system to overcome the limitations of traditional cardiac monitors. His journey in healthcare began as a combat medic for the U.S. Army, and he later applied his focus on introducing new technologies to answer significant unmet medical needs. The company's goal was to provide continuous, heartbeat-by-heartbeat monitoring for patients outside of a hospital setting, allowing for quicker diagnosis and treatment of potentially life-threatening arrhythmias that are often difficult to detect.

The core of the business is the Mobile Cardiac Outpatient Telemetry (MCOT™) system. This system uses a patient-worn sensor to capture ECG data, which is then wirelessly transmitted to a monitor that analyzes the information using proprietary algorithms to detect arrhythmias. This data is sent in real-time to a 24/7 monitoring service center, enabling prompt physician reporting and urgent response. CardioNet primarily serves the healthcare and clinical research sectors, catering to physicians, medical professionals, and clinical trials that require cardiac monitoring. The business model focused on providing these monitoring services, billing for Holter monitoring, event monitoring, and MCOT services. In addition to its direct patient services, the company expanded into clinical research services, providing cardiac monitoring for pharmaceutical and medical device trials.

CardioNet achieved several key milestones, including receiving FDA approval for its MCOT technology in 2002 and going public with an IPO in March 2008. The company grew through strategic acquisitions, including PDSHeart in 2007 and Biotel, Inc. in 2010, which expanded its product portfolio to include a full spectrum of arrhythmia monitoring solutions. In 2013, to better reflect its broadening scope beyond cardiac monitoring into other areas of mobile health, CardioNet restructured, adopting the name BioTelemetry, Inc., with CardioNet becoming an operating subsidiary. BioTelemetry continued to expand, and in February 2021, it was acquired by Royal Philips for an enterprise value of approximately $2.8 billion. This acquisition integrated BioTelemetry's remote cardiac monitoring leadership with Philips' extensive patient care management portfolio.
