Tom Wong is a 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. He completed the postgraduate fellowship in Electrophysiology and Pacing at St. Mary’s Hospital, London in 2005. He was then appointed as the consultant cardiologist and electrophysiologist at the Royal Brompton and Harefield Hospitals in 2006.

His career focused on seeking and providing the best care to patients with heart rhythm abnormalities 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. He conducted ARC-HF clinical trial (NCT00878384), 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 patients at risk of stroke. He completed NIHR funded, CASA-AF randomised control trial (NCT02755688), which is the first to show that catheter-based ablation to treat longstanding persistent atrial fibrillation is as effective as surgical approach. In addition, his research group continues to investigate novel mapping, ablation, and device related technologies with an aim to improve clinical outcomes.
