Research profile and interests

Dr Lim completed a PhD in clinical electrophysiology at Imperial College London. His research focussed on exploring the role of the autonomic nervous system in human atrial fibrillation. He has been awarded several prizes for his pioneering work inlcuding the President's Medal for Cardiology at the Royal Society of Medicine, the Lindo Foundation Prize at St Mary's Hospital, and Runner-up Prize in the Young Investigator Award for the British Cardiovascular Society, and Asia Pacific Heart Rhythm Society Meetings.

Since succesfully completing his PhD, Dr Lim has continued to be actively involved in research at the National Heart and Lung Institute, Imperial College London, and continues to supervise several PhD students. As the clinical lead for the Imperial Syncope Diagnostic Unit, he is regularly invited to speak on Blackouts, Faints, Postural orthostatic tachycardia syndrome, and syncope - including novel ideas of treatment, informed by a greater understanding of the underlying mechanisms underscoring vasovagal syncope.

Dr Lim continues to explore novel aspects of ablation, and is currently looking exploring the role of modulation of the autonomic nervous system as a treatment strategy to treat atrial fibrillation and selected patients with vasovagal syncope. This technique aims to dampen the "flight or fright" response which may be responsible for triggering syncope attacks or blackouts.

He has developed strong industry links and collaborations with major partners, including Medtronic, St Jude Medical and Boston Scientific, to advance state-of-the-art technologist in treating arrhythmias, including atrial fibrillation. He is often asked to speak on these novel 3D mapping technologies at National and International Conferences.  

Dr Lim leads the Imperial Syncope Diagnostic Unit as principal investigator for several clinical trials, including NIHR portfolio studies of best drug treatments for syncope, and is setting up an autonomic ablation trial for difficult-to-treat resistent syncope. In particular, young and otherwise fit and healthly patients, who have cardioinhibition (i.e slow heart beart or significant pauses heart rhythm) causing syncope, may benefit by abolishing the need for pacemaker implantation in this group.
