Founded as CardioNet in San Diego in 1994, BioTelemetry developed mobile cardiac monitoring technology and now provides connected ECG services and devices that help clinicians diagnose and manage arrhythmias beyond the hospital. Its signature MCOT system supports up to 30 days of monitoring, with cardiac technicians reviewing reports, while the company’s broader platform connects patient data to clinical workflows and electronic medical records. BioTelemetry became part of Philips in 2021 and is now externally known as Philips Ambulatory Monitoring & Diagnostics.
