About Us

The Holter Monitoring Service is provided by two experienced UK cardiologists with a broad range of expertise, both working as Specialists at Dick White Referrals, a multidisciplinary referral centre in Cambridgeshire. A strength of the service is the access to very many years combined experience in Specialist referral practice and, where appropriate, multidisciplinary input from other Specialists within the practice.
