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.

Dr Behar did a full cardiological review following a very low heart rate and arrythmia diagnosed during a pre-op for a minor surgery which was unable to progress. Dr Behar's initial check indicated no major concerns but to ensure nothing was missed and there were no underlying concerns a full assessment was performed. Dr Behar kept me informed throughout and provided me with a full and detailed explanation of all the results in writing and in person and answered all remaining questions I had. Excellent professional and personal care throughout and highly recommended.

I was very impressed and grateful for the calm efficiency from the moment I stepped into the Hospital. It was so very reassuring. I am 90 years and have bad arthritis, and was given a wheel chair immediately I arrived. I was taken to a quiet, calm efficient person who took my details. Then given a cup of coffee. Dr Behar saw me On Time and gave me 35 minutes of unhurried Medical information and advice. Fortunately it was all Good News ! My Blood Pressure has come down, and my heart does not need a pacemaker ! I am so impressed and grateful to Dr Behar and the Hospital. Mega Thanks !

Seeing Dr Behar was a far more pleasant experience than it could have been. I was quite anxious when I saw the doctor but he put my mind at rest, he was warm and sympathetic and I would be very happy to recommend him to anyone who needs the services of a Cardiologist.
