Personal profile

Dr Fu Siong Ng is a Clinical Lecturer in Cardiology at Imperial College London, and a consultant cardiologist at Imperial College Healthcare NHS Trust and at Chelsea and Westminster Hospital NHS Foundation Trust. He is a clinician scientist and divides his time between treating patients with heart rhythm disorders by performing invasive catheter ablation procedures and implanting pacemakers and defibrillators, and directing research into mechanisms of arrhythmias and developing novel therapeutic strategies. 

Dr Ng studied medicine at St. George’s, University of London between 1997 and 2003. He was awarded a first class (honours) BSc degree in medical sciences and clinical pharmacology, having ranked top in his year in multiple examinations, and then obtained distinctions at his final MBBS examinations. He then received his clinical training in cardiology and cardiac electrophysiology at several London hospitals, including Hammersmith and St. Mary’s hospitals. Dr Ng was awarded his PhD by Imperial College London in 2012 after conducting studies into the effects of gap junction modulation on myocardial structure and function. He then spent a year conducting post-doctoral research in the USA, at Washington University in Saint Louis, conducting optical mapping experiments on explanted human hearts. Dr Ng is also an accredited cardiac electrophysiology specialist by the European Heart Rhythm Association.

Dr Ng is actively engaged in arrhythmia research and is currently co-principal investigator on a five-year British Heart Foundation (BHF) funded programme grant on myocardial fibrillation. He is associate director of Imperial Centre of Excellence in cardiac engineering and executive director of the ElectroCardioMaths Programme at Imperial College London. He has attracted over £2 million in external research funding, including BHF-funded programme and project grants and fellowships from the Medical Research Council and National Institute of Health Research. He has published >40 peer-reviewed papers and has won 14 research prizes, including at young investigator competitions at the British Cardiac Society and Heart Rhythm Congress. He has supervised six PhD students at Imperial College, two of which have been awarded and four are ongoing. 

Dr Ng’s research spans the bench-to-bedside spectrum, from benchtop high-resolution optical mapping experiments on myocardial tissue, to computational modelling of arrhythmias, through to first-in-man invasive electrophysiological studies in humans. 

His current research interests include:

  • Investigating the electroarchitectural determinants of myocardial fibrillatory dynamics (experimental) 
  • Investigation of ursodeoxycholic acid as an anti-fibrotic and anti-arrhythmic agent (experimental) 
  • The role of the Purkinje-myocardial junctions in ventricular arrhythmogenesis (experimental) 
  • First-in-man studies on low-energy defibrillation for atrial fibrillation (clinical) 
  • Risk stratification in inherited cardiac conditions using non-invasive electrocardiographic imaging (clinical) 
  • Ultra high-resolution mapping of atrioventricular junction physiology (clinical) 
  • Modelling the spatial resolution required for tracking of fibrillatory drivers (computational)
