RhythMedix

RhythMedix is a private U.S.-based cardiac monitoring company focused on ambulatory ECG and remote patient monitoring. Its core commercial offering is the RhythmStar wearable cardiac monitoring system, which combines built-in cellular connectivity, arrhythmia-detection algorithms, and associated monitoring/reporting services to support clinicians in diagnosing irregular heart rhythms. The company operates in medical devices and connected diagnostics rather than therapeutics, with a focus on cardiology workflow, patient compliance, and faster transmission of monitoring data. RhythMedix appears to be commercially active and was acquired by Pharos Capital Partners/Pharos Capital Group, which continues to list it as a current portfolio company. The business is headquartered in Mount Laurel, New Jersey and serves healthcare providers managing patients with suspected or known cardiac rhythm disorders.
