Dr Fu Siong Ng is a Clinical Senior Lecturer in Cardiac Electrophysiology at Imperial College London, and a Consultant Cardiologist at Imperial College Healthcare NHS Trust and Chelsea and Westminster Hospital NHS Foundation Trust. He is a Clinician Scientist and currently leads a programme of research into arrhythmogenic mechanisms alongside performing invasive ablation procedures and implanting pacemakers and defibrillators in patients with heart rhythm disorders. Dr Ng is also the Programme Director for the intercalated BSc in Cardiovascular Sciences at Imperial College London, and is the Divisional Research Lead for the Division of Emergency & Integrated Care at Chelsea and Westminster Hospital NHS Foundation Trust. 

Dr Ng studied Medicine at St. George’s, University of London, where he was awarded a First Class (Honours) BSc degree in Medical Sciences & Clinical Pharmacology and achieved Distinctions at his Final MBBS Examinations. He received his post-graduate clinical training in Cardiology and Cardiac Electrophysiology at Hammersmith and St. Mary’s Hospitals. Dr Ng was awarded his PhD by Imperial College London for his work on the effects of gap junction modulation on the post-infarct arrhythmic substrate, funded by an MRC Clinical Research Training Fellowship. He then conducted post-doctoral research at Washington University in Saint Louis, funded by a BHF Travel Fellowship, investigating the arrhythmogenic remodelling in heart failure by performing optical mapping experiments on explanted human hearts, before returning to Imperial, firstly as an NIHR Clinical Lecturer and now as a Clinical Senior Lecturer. Dr Ng is accredited as a Cardiac Electrophysiology Specialist with the European Heart Rhythm Association and is a Fellow of the European Society of Cardiology.

Dr Ng is currently an Executive director of the ElectroCardioMaths Programme. He has attracted >£3 million in external research funding, published >70 peer-reviewed research papers and won 14 research prizes.

Dr Ng’s research spans the bench-to-bedside spectrum, and his current research interests include:

  1. The electroarchitectural determinants of myocardial fibrillatory dynamics (PhD student: Balvinder Handa, post-doc: Xinyang Li)
  2. The role of inflammation and auto-immunity on arrhythmogenesis (PhD student: Catherine Jenkins, post-doc: David Pitcher)
  3. Ventricular electrophysiological remodelling in bariatric patients and in DCM patients with titin-truncating mutations (PhD student: Kiran Patel)
  4. First-in-man studies on low-energy defibrillation for atrial fibrillation (link)
  5. Ursodeoxycholic acid as an anti-fibrotic and anti-arrhythmic agent (PhD student: Elisa Ferraro)
  6. The role of the Purkinje-myocardial junctions in ventricular arrhythmogenesis 

Dr Ng is active in both undergraduate and postgraduate teaching and supervision at Imperial and has supervised 9 PhD students at Imperial.
