Dr Reginald Liew is a cardiologist at Gleneagles Hospital and Mount Elizabeth Hospitals, Singapore.

He is trained in cardiac electrophysiology (EP) procedures such as catheter ablation (radiofrequency energy that rectifies abnormal heart rhythm) using conventional and 3D mapping systems. He also performs cardiac device implantation, such as cardiac pacemakers, implantable cardioverter defibrillators (ICD) and cardiac resynchronisation therapy (CRT) devices.

He undertook his medical training at Cambridge University, and Guy's and St Thomas' Hospital, graduating with distinction. He obtained a PhD from Imperial College London, where he investigated the effects of oestrogens on the heart, and received his cardiology training at the Royal Brompton Hospital and subspecialty training in cardiac arrhythmias at St Bartholomew’s Hospital and St George’s Hospital in the UK.

He has been active in the field of heart rhythm problems, and was involved in some of the early clinical studies in the UK that validated the use of 3D mapping systems to treat complex heart rhythm problems.

Dr Liew was the former senior consultant and deputy director of the research and development unit at the National Heart Centre, where he helped develop the research programme, especially in the fields of cardiac arrhythmias and the use of stem cells in cardiovascular disease. His research interests include atrial fibrillation, cardiac risk assessment, and sudden cardiac death. He is also a member of the research committee for the Singapore Heart Foundation and the basic science committee of the Asian Pacific Heart Rhythm Society.

He is a keen health educator and has mentored cardiologists in Singapore and in countries like the UK in performing cardiac EP procedures, and regularly proctors EP cases in neighbouring countries.
