Welch Allyn

Welch Allyn, previously a privately-held, family-owned manufacturer of Holter Monitoring devices and solutions, was acquired by Baxter – Hillrom and now operates under their umbrella. The company continues to collaborate with long-time Holter monitoring company Mortara Instruments.

Throughout its history, Welch Allyn has remained committed to developing products that enhance lives and simplify the assessment and diagnosis process for medical professionals. They achieve this by employing innovative Holter Monitoring technologies, enabling frontline practitioners to work more effectively and efficiently with their patients at the point of care.

Welch Allyn’s suite of Holter Systems offers user-friendly software and recorders that promote patient compliance due to their lightweight and compact design. The systems can be customized using Welch Allyn Office Holter software or Welch Allyn Expert Holter software, and they feature a compact digital recorder capable of 2- or 3-channel recording for detailed evaluations. Both systems deliver fast and accurate data, streamlining workflows and ensuring compatibility with electronic health record systems (EHRs) to enhance overall practice efficiency.

Competitive Advantage in Holter Monitoring
