Oracle Healthcare Cardiology provides comprehensive and compassionate care for patients with cardiac concerns in a state-of-the-art facility on Sydney’s lower North Shore
The heart is a vital organ so any concerns about its function should be taken seriously. Stroke, heart and blood vessel disease are the leading cause of early death in Australia, accounting for one in four deaths.
Knowledge is power, though. That’s why we take a proactive approach to preventing, identifying and treating cardiovascular diseases.
Oracle Healthcare Cardiology boasts a skilled team of general and interventional cardiologists who provide timely, high-quality care, build a strong rapport with their patients and communicate fully and promptly with referring GPs.

At Oracle Healthcare Cardiology, we go beyond traditional cardiac care by integrating the latest technology with a comprehensive, interdisciplinary approach. Our advanced diagnostic tools include exercise tests, echocardiograms, remote monitoring devices, and blood pressure assessments providing valuable insights into heart function.
But data alone isn’t enough. We combine objective diagnostics, expert clinical insights, and evidence-based lifestyle medicine to create truly personalised care plans. Unlike many cardiology clinics that refer out for additional support, our team includes dietitians, exercise physiologists, and allied health professionals who work collaboratively to help patients manage existing conditions and reduce their risk of future cardiac events. This integrated approach ensures patients receive seamless, holistic care tailored to their unique needs – all in one place.
Vine Holter Monitoring
Our cardiologists can refer in-house for Holter Monitoring Services. Our nurses will fit the devices in-clinic and give a detailed explanantion of the process and any care instructions. Results are reported directly to back our Cardiologists, and patients may call our team with any questions or concerns.
24 Hour Ambulatory Blood Pressure Monitoring
In-house 24-hour Ambulatory Blood Pressure Monitoring can be organised for patients. Our experienced nurses will fit the device on-site, providing a clear explanation of the process and any necessary care instructions. Once the monitoring period is complete, results are sent directly to our cardiologists for review. Patients are welcome to contact our team with any questions or concerns throughout the process.
Our Cardiology team understands that your time is precious. We’re proud to promote that 99% of our appointments run on schedule, ensuring you are seen at your booked time, with minimal waiting. We understand firsthand how frustrating delays can be, which is why we prioritise efficiency without compromising on quality care.
Unlike many practices, we rarely have a waiting list. We allocate time for urgent cases, ensuring those in need receive same-day appointments whenever possible. This proactive approach helps prevent unnecessary emergency department visits, providing timely care when it matters most.
All patients require a referral to see a cardiologist.
If you already have a current referral, please book an appointment. If you do not, please see your GP and ask to be referred to Oracle Cardiology.
We deliver exceptional clinical care, a positive patient experience and prompt reports to referring doctors.
With same-day appointments often available, we encourage you to refer your patients to Oracle Healthcare Cardiology.
