John J. Atherton is a cardiologist based in Herston, QLD. You can find the practice at Butterfield St, Herston QLD 4029, Australia. As a heart specialist, John helps people with a wide range of heart and blood vessel problems, from day-to-day management to urgent, time-critical issues.
In many cases, patients see him when they have symptoms like chest pain, shortness of breath, fainting or feeling like their heart is racing or skipping beats. He also looks after people with heart failure, including heart failure with preserved ejection fraction (HFpEF). If the heart muscle is affected, John works with conditions such as cardiomyopathy, including hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). Familial forms of these conditions can also come up, where there may be a family link and long-term heart monitoring matters.
John also treats rhythm and electrical system problems. That can include atrial fibrillation, paroxysmal supraventricular tachycardia (PSVT), and longer-term electrical issues like long QT syndrome. At times, people are referred after serious events such as a heart attack, cardiac arrest, or acute coronary syndrome. He may also be involved in planning care around coronary heart disease and procedures such as percutaneous coronary intervention (PCI).
Other heart-related issues can include valve problems like tricuspid regurgitation, plus related conditions where blood levels can affect the heart’s rhythm, such as high potassium levels or low sodium levels. John’s care may also connect with broader health problems that can sit alongside heart disease, including type 2 diabetes (T2D). In some situations, people are also managing other complex health topics, and the goal is to keep the heart part steady and well supported.
Information about education, work history, research, and any clinical trials isn’t listed here. Still, the focus stays on practical heart care—helping patients understand what’s going on, what the next steps are, and how to manage risks over time.
