Shobi Sivathamboo is a Cardiologist based in Melbourne, VIC, Australia. They look after people who have heart rhythm problems and other issues where the heart’s timing and electrical signals matter.
In many cases, patients come in after episodes like palpitations, feeling faint, or shortness of breath. Some people are also dealing with sleep-related breathing problems, and it can affect how the heart behaves during the night. Dr Sivathamboo focuses on sorting out what’s going on, checking the heart thoroughly, and making a clear plan for follow-up.
Heart rhythm issues are a big part of the work. This can include fast heart rhythms such as paroxysmal supraventricular tachycardia (PSVT), and other arrhythmias. At times, patients also seek care after something more urgent, such as cardiac arrest, or when there’s a concern about how well the heart muscle is working.
There are also situations where symptoms can be confusing. Some people have events described as seizure-like episodes, absence seizures, or generalised tonic-clonic seizures, and others have central sleep apnoea. Hyperventilation can be involved too. In these cases, the goal is not to jump to conclusions. Dr Sivathamboo works to make sure the heart is checked as part of the bigger picture, especially when symptoms might overlap.
Care may also include looking at conditions such as restrictive cardiomyopathy (RCM) and familial dysautonomia. Sometimes, people have ongoing challenges like conversion disorder or Lennox-Gastaut syndrome (LGS), and they need careful medical support while other causes are reviewed. The approach is calm and practical, with attention to both day-to-day symptoms and any risks that could show up during an episode.
Over time, Dr Sivathamboo’s clinical work has covered a mix of rhythm problems, urgent heart events, and long-term health concerns. The focus stays on steady assessment, appropriate testing, and clear next steps. If you’re unsure where your symptoms fit, it can still be worth getting the heart side of things checked.
Appointments are available in Melbourne for people who need a cardiology opinion and hands-on, real-world management of heart-related symptoms.
