About Dr Jonathan Behar

Dr Jonathan Behar is a Consultant Cardiologist with a specialist interest in managing patients with heart rhythm disturbances. His is based at Guy's and St Thomas' NHS Foundation Trust where he is also a Senior Clinical Lecturer within the Department of Imaging Sciences, Kings College London.

He graduated with honours from the Royal Free and University College Medical School before specialising in general medicine and cardiology in north London. He trained in cardiac rhythm management at the Barts Heart Centre and was a Locum Consultant at the Royal Brompton and Harefield Hospitals before taking up his current position.

He performed pioneering research collaborating with engineers, industry and clinical teams which led to the co-invention an image guidance platform that integrates MRI and X-rays in real-time for personalising the care of patients undergoing cardiac procedures. This work was nominated for a European Innovation Award in 2017.

Dr Behar has a passion for addressing unmet clinical needs through translational and innovative solutions. He was an NHS England Clinical Entrepreneur Fellow and recently led a team which digitised pre-operative consent for patients undergoing cardiac procedures. This work won the Royal College of Physicians Digital Award for Excellence in Patient Care 2021.

Dr Behar sees patients with a whole range of cardiac complaints including palpitations, dizziness, fainting, chest pain and breathlessness. He also manages patients with high blood pressure and high cholesterol.  He performs catheter ablations for a range of arrhythmias with a particular interest in new technologies for the treatment of atrial fibrillation. He is highly experienced in the implantation of cardiac devices (pacemakers, defibrillators and cardiac resynchronisation therapy) including the latest, miniaturised leadless pacemakers.

I cannot recommend Dr Jonathan Behar highly enough. I recently had a follow up appointment with him after undergoing treatment last year, and once again I was extremely impressed with the care I received. Dr Behar is very thorough, takes the time to listen and is always happy to answer any questions or concerns. The treatment and care he has provided have been exceptional, and most importantly, the outcome has been incredibly positive, whilst there are no long-term guarantees, I am currently free of atrial fibrillation. I am extremely grateful to Dr Behar and his team for the excellent care and treatment I have received and would have no hesitation in recommending him to anyone requiring specialist cardiac care.

Dr Behar took the time to explain things and put me at ease. (I can be a nervous patient) He listened to my concerns and no question was dismissed as not relevant. His, and his team's, care have been excellent and I feel so much better. Thank you
