Your consultation with Dr. Boon Lim, consultant cardiologist and renowned highly-rated expert in arrhythmias and syncope, and author of Keeping Your Heart Healthy, a Penguin Life Expert book.

Dr. Boon Lim was first voted best cardiologist in London UK by colleagues in 2017. Dr Boon Lim was again awarded Top Doctor of the year in 2018 and 2021 for cardiology, making Dr Lim the most awarded cardiologist on Top Doctors voted by physician peers across the UK. He provides personalized patient care, tailored to your needs and works in the NHS based at Hammersmith Hospital, a renowned academic teaching hospital, and also as a private cardiologist at 1 Welbeck Street in central London.

Dr Lim is a highly reviewed cardiologist, and his patients consistently rate him highly as a kind and holistic doctor, who has excellent technical skills to conduct ablation procedures to cure heart rhythm disorders such as Atrial Fibrillation and SVT.

Dr. Lim is able to see you at several locations for your convenience, where you can expect to receive world-class care. Consultation starts with a history and thorough understanding of your needs and often fears, and his empathetic style, and clear decision-making, underscored by expert knowledge in his field, give patients the assurance and confidence that they are receiving an exceptional healthcare experience entirely focused on the patient’s concerns.

Furthermore, Dr Boon Lim is dynamic, going against the traditional model of private healthcare with frequent or annual checks. He would much rather help you get back to full health and thereafter discharge you completely with the reassurance that you could seek a review or further follow-up appointment when necessary.
