Mark O'Neill: Consultant Cardiologist in London

Professor Mark O'Neill is a Consultant Cardiologist and Professor of Cardiac Electrophysiology who sees private patients at The Cardiac Clinic at London Bridge Hospital. Fellowship trained in cardiac electrophysiology, he is an internationally recognised expert in catheter ablation of atrial fibrillation and tachycardia. He was appointed a Professor in 2013 and has since then led the arrhythmia service, the regional training program and the cardiac electrophysiology divisional research program. He was awarded a National Bronze Clinical Excellence award in 2016 and in 2021 in recognition of the quality and breadth of both his clinical and academic work. Professor O'Neill treats patients with all kinds of heart palpitations, including those caused by simple and complex heart rhythm conditions, such as supraventricular tachycardia, atrial fibrillation, atrial flutter/tachycardia, arrhythmias associated with adult congenital heart disease and ventricular tachycardia. He takes the time to help his patients understand fully their symptoms and works with them to develop tailored treatment plans, including interventional electrophysiology procedures where necessary.
