Dr Tom Wong is Consultant Electrophysiologist and Cardiologist at Royal Brompton and Harefield NHS Foundation Trust. He is the clinical lead of the Arrhythmia Services and the research lead of the Arrhythmia Group across the Royal Brompton and Harefield sites. 

He graduated from University of Aberdeen in 1993, underwent cardiology and electrophysiology training in London, before his consultant appointment in 2006.

Dr Tom Wong’s career focuses on providing the best clinical care to patients with heart rhythm abnormalities and exploring avenues to further improve care through research and innovation. 

His research program relates to his clinical interests to seek better understanding and treatment of arrhythmias in advanced disease states and complex cardiac anatomies.

Dr Tom Wong conducted ARC-HF clinical trial, first to show the beneficial effects of catheter ablation in cardiopulmonary performance compared to drug therapy in patients with persistent atrial fibrillation and heart failure. He published the cost impact of the left atrial appendage closure in stroke prevention based upon the UK cost model to inform the economic benefit, beyond the clinical needs, of this treatment to patient at risk of stroke. He is the chief investigator of CASA-AF trial, funded by NIHR, to compare catheter and thoracoscopic ablation approaches to treat persistent atrial fibrillation. In addition, he has and continue to investigate novel mapping, ablation and device related technologies with an aim to improve clinical outcomes.
