What is Dysautonomia?

Dysautonomia is a condition that affects the autonomic nervous system which controls many of the unconscious functions of the body such as heart rate, blood pressure, sweat, bladder and bowel function.
There are several sub-types of dysautonomia. The most common of these are ‘orthostatic intolerance’ and ‘postural orthostatic tachycardia syndrome’ (POTS).

POTS is a complex condition that affects multiple body systems. It is characterised by a rapid heart rate when moving from sitting to standing as well as other symptoms such as dizziness, blurred vision, and faintness.

THE Integral Healthcare POTS Clinic

POTS Multidisciplinary Assessment Clinics


At Integral Healthcare, we strive to provide a welcoming environment where the complex health needs of our patients can be discussed in a safe and understanding environment.

We are committed to working collaboratively with other specialists and allied health professionals to provide a comprehensive management plan to improve health outcomes for those who journey with this complex syndrome. 

While the clinic focuses on treatment of POTS, we also have experience with managing the cardiac impacts of other associated conditions such as Hypermobile Spectrum Disorders, Chronic Fatigue Syndrome, and Long-Covid Syndrome.

Multidisciplinary Assessment (MDA) Cardiology Clinic

Dysautonomia is a complex and difficult to treat, disorder. An initial, thorough assessment at our MDA clinic is required to ensure a correct diagnosis and to provide optimal understanding of the most appropriate treatment options for patients.

An appointment with our Multidisciplinary Cardiology Clinic requires a referral from a General Practitioner or specialist doctor.

Attendance at the MDA clinic involves a consultation with Dr Dennis Lau (Cardiologist/Electrophysiologist), diagnostic studies and an assessment with our Clinical Nurse.

Before attending our MDA clinics, patients may be asked to undertake some diagnostic tests. These vary according to the individual but may include:

  • Holter monitor
  • Echocardiogram
  • ECG
  • Tilt Table Testing

Those taking medications to control heart rate may be asked to stop these for various tests. Please confirm with administration staff when booking your appointment.

Multidisciplinary Assessment (MDA) GP Clinic

Dysautonomia can cause various chronic health issues that may appear unrelated, and which can be difficult to diagnose. Our Multidisciplinary GP Clinic provides a thorough assessment, as well as pathology and diagnostic screening for other associated conditions where appropriate.

All patients will be seen by our Clinical Nurse who provides a patient-centred approach to education on health management and treatment options. Where appropriate our GP and nurse can assist in developing chronic health management plans.
Appointments with our Multidisciplinary GP Clinic can be made without a referral. Where required, our GP may refer patients to Dr Lau, other medical specialists and allied health practitioners for further evaluation and health management. 

Making an Appointment

If you already have a referral from a GP or specialist to see Dr Lau, please call our clinic to make an appointment.

If you don’t have a referral, you may call our clinic to make an appointment to attend our Multidisciplinary Clinic where you can see our GP and nurse without a referral.

What to bring

To get the most out of your appointment we ask that you bring any previous medical test results or other relevant medical


We understand that those with chronic illness often find medical appointments difficult. We encourage you to bring a support person to your appointment if you feel this would be beneficial.

If you have not already done so, please complete our Patient Survey prior to your first visit.
