Diagnostic Tests

Outpatient referrals for diagnostic cardiac catheterization or angioplasty must be made by a cardiologist. To refer a patient, complete the Patient Registry Form (pdf) and fax to 613-696-7144.

For questions or to advise of changes in patient status, contact the Regional Cardiac Care Coordinator at 613-696-7000 x19733.

Outpatient referrals for diagnostic tests can be made through Ocean eReferral, which enables most community physician EMRs to conveniently create and submit requisitions directly. If you are not already set up with access to Ocean eReferral and are interested in learning more, please contact Champlain_eReferral_Team@lhins.on.ca.
