Other

  • Pacemaker/ICD
    • delivery of 2 or more shocks by ICD in 24 hours
    • suspected pacemaker/defibrillator malfunction (with ECG evidence)
    • pacemaker/ICD device erosion
  • Bradycardia including any of the following:
    • symptomatic bradycardia
    • PR interval on ECG exceeding 300ms
    • second degree or complete heart block
  • Broad complex tachycardia
  • Suspected or confirmed endocarditis, myocarditis or pericarditis
Useful Management Information
  • Not all patients have to be seen by a cardiologist if the general practitioner is comfortable caring for the patient. 
  • In patients with new onset atrial arrhythmias (<48 hours), consider a fast track approach via telephone contact with the nearest cardiology service for consideration of earlier cardioversion to minimize the burden of atrial arrhythmia.
Minimum Referral Criteria

Category 1
(appointment within 30 calendar days)

 

  • New atrial fibrillation/flutter without Red flags (see below)
  • Recurrent paroxysmal atrial fibrillation / flutter
  • Atrial fibrillation with signs of heart failure or reduced LV function that does not require presentation to Emergency

 

Absence of Red flags - if below red flags are present, please refer the patient to the emergency department (via ambulance if necessary) or seek emergent medical advice if in a remote region:

  • Atrial fibrillation / flutter with any of the following Red flags
    • haemodynamic instability
    • shortness of breath
    • chest pain
    • syncope/pre syncope/dizziness
    • known Wolff-Parkinson-White
    • neurological deficit indicative of TIA/stroke
Category 2
(appointment within 90 calendar days)
  • Chronic atrial fibrillation requiring management review (e.g. rate control, anticoagulation)
Category 3
(appointment within 365 calendar days)
  • No Category 3 criteria

Essential referral information

Without this information the referral will be returned

  • Details of relevant signs and symptoms
  • Details of all treatments offered and efficacy
  • Past medical history and comorbidities
  • Family history of cardiac disease or sudden cardiac death
  • FBC, ELFTs, TSH results
  • Include available ECGs, in particular those demonstrating the arrhythmia
Additional Referral Information
  • Any investigations relevant to any co-morbidities
  • Other investigations (if available) eg echocardiogram report, CXR report, holter monitor report, sleep study report
  • History of smoking, alcohol intake and drug use (including recreational drugs)
  • Coagulation studies, fasting lipid results
  • CHA2DS2 VASC score
Clinical Override

Clinical override of referral criteria may be requested in the following situations:

  • Inability to include essential referral information. If a specific test result is unable to be obtained due to access, financial, religious, cultural or consent reasons.
  • Patient does not meet minimum referral criteria. If the patient does not meet the criteria for referral but the referring practitioner believes that the patient requires specialist review.
  • Presence of clinical modifiers. The presence of clinical modifiers (as listed above in Standard referral information) may impact on the categorisation of a patient.

Include the reason for request for clinical override as part of the referral. Referrals are reviewed by the triaging specialist who determines the most appropriate course of action.

Out of catchment

West Moreton Health is responsible for providing a public health service to people who reside within its catchment area. To appropriately manage demand for service we do not accept referrals from outside this catchment area. If your patient does live outside the West Moreton Health area and it is deemed socially or clinically necessary for their care to be received in the West Moreton Health Service, inclusion of information regarding their particular medical and/or social factors will assist with the triaging of your referral.
