Marie-claire Seeley is a cardiologist based at Port Road in Adelaide, SA 5000. She works with people who have ongoing heart rhythm and circulation concerns, and also with those dealing with body-wide symptoms that can go along with them. Many patients come in feeling unsure about what is going on, especially when symptoms change day to day.
Her clinic care includes conditions like postural orthostatic tachycardia syndrome (POTS) and arrhythmias. She also looks after people with familial dysautonomia and neuro-related hormone issues, such as diabetes insipidus (DI) and neurohypophyseal diabetes insipidus. At times, her patients also have long haul COVID, and some have had severe acute respiratory syndrome (SARS) in the past. She understands how these conditions can affect the heart rate, blood flow, and how you feel when you stand, move, or try to sleep.
Because POTS and some related conditions can be linked to both heart signals and the way the nervous system controls the body, care often needs a careful, steady approach. Marie-claire focuses on listening to the story, checking what’s happening with your heart and symptoms, and making a practical plan for day-to-day management. In many cases, it’s about finding patterns, tracking triggers, and helping patients feel more in control.
She also supports people managing diabetes, including gastroparesis and other stomach or energy issues that can show up alongside long-term health problems. That matters, because the heart and body don’t always work in neat boxes. Over time, she helps patients connect the dots between symptoms, medications, and lifestyle changes.
In terms of experience, Marie-claire has clinical experience caring for people with complex, long-lasting conditions where the heart and symptoms are closely linked. Her approach is calm and grounded. She takes time with each person and doesn’t rush the process, especially when tests and answers take a while.
Her medical background includes training in cardiology, and she keeps learning with current guidance and new findings. She also reviews relevant research in a simple, practical way, so decisions are based on what’s helpful for real patients, not just guidelines on paper.
