    • abnormal ECG (e.g. LV hypertrophy, AF, LBBB, RBBB)
    • fever or constitutional symptoms suggestive of infection (eg endocarditis, acute rheumatic fever)
    • signs of heart failure

Murmur (paediatric)

  •  Infant <3 months with newly noted murmur and any of the following concerning features:
    • poor feeding
    • slow weight gain
    • weak or absent femoral pulses
    • post ductal (foot) oxygen saturation < 95%
    • respiratory signs (wheeze, recession or tachypnoea)

Palpitations

  • Palpitations with any of the following concerning features:
    • chest pain
    • shortness of breath

Named referrals

If you would like to send a named referral, please address it to the specialist on the referral template, who will allocate a suitably qualified specialist to see the patient.

From July 1 2017 Commonwealth growth funding has been capped. This changes how WMHS can fund its growth as an organisation. Named referrals from GP’s help support hospital funding through a Medicare bulk-billing arrangement. The new federal funding model incorporates specific pricing for patients which removes concerns around ‘double dipping'. This benefits hospital and patient services.


Patient must bring

  • Medicare card
  • Any concession cards (e.g. Pension, Health Care, DVA, PBS Safety Net, ADF, etc)
