Welcome to the Hornsby Cardiac Diagnostic Unit


Hornsby Cardiac Diagnostic Unit is a specialist medical practice which has been providing complete cardiac diagnostic and therapeutic services to patients on the North Shore of Sydney and surrounding areas for over 25 years.


For most new consultations, and for referrals for diagnostic testing, appointments are usually available within one to two weeks. If it is felt your problem is more urgent, a phone call from your GP to one of our doctors will facilitate an earlier appointment. Reports from your consultation and test results are forwarded promptly to your referring doctor.
