Personal profile

Dr Lim is an experienced consultant cardiologist and electrophysiologist, who works in his NHS practice based at Imperial College Healthcare, at Hammersmith Hospital, as well as at Chelsea and Westminster Hospitals based at West Middlesex Hospital. He is also an honorary senior lecturer based at Imperial College London.

Dr Lim has a clinical and research interest in atrial fibrillation, the most common cardiac arrhythmia, and is developing novel tools and techniques to more effectively treat patients with this heart rhythm disturbance. By using state of the art 3D mapping technology, Dr Lim is able to study areas of the heart which may be responsible for driving atrial fibrillation, to then target these areas during ablation procedures to improve cure rates for patients with this condition.
Dr Lim is also the clinical lead for the Imperial Syncope Diagnostic Unit one of the busiest and most highly regarded syncope units in London, and the UK. He has a particular interest in patients with difficult-to-treat syncope and offers advice, education and specific therapies which empowers patients to take control of their symptoms.

Dr Lim has an active research program researching strategies to improve treatment for vasovagal syncope, which includes trials of drug therapy with international collaborators, and is studying the physiology of syncope by scrutinising data from tilt table testing to better understand why people faint, and how treatment can be developed to improve symptoms. He has published numerous articles on treatment for syncope, and is frequently invited to speak at National and International meetings to share his experiences in helping treat patients with syncope.

He is rated one of the best educators and teachers by his trainees at Imperial College, particularly for his teaching in the arrhythmia and syncope clinic which he runs weekly.

Dr Lim is highly rated by patients, junior doctors, and colleagues.
