Recommended by:

  • byDr Elaine Tickle, GP

    ❝Dr Segal is an excellent cardiologist specialising in Electrophysiology. I have found his approach to patients to be thorough and timely. He is sensible and very able to explain to patients what the problems are and how they might best be solved. His precision for ablation seems high - none of the patients he has treated have slipped back to dysrhythmias. In short, I have no hesitation in referring patients to Dr Segal and would be happy for him to look after me or my family.❞

  • byDr Jonathan Howard Sheldon, GP

    ❝I have referred many patients to Dr Segal. He is a good General Cardiologist but also has an interest in arrhythmias and always gives an excellent opinion. Patients give very good feedback; he is responsive and a good communicator and I have no reservations in recommending him.❞

    About Dr Oliver Segal

    GMC number: 4209250

    Year qualified: 1995

    Place of primary qualification: University of London

    Dr Oliver Segal is a distinguished heart specialist, focusing on cardiology and electrophysiology. He practices privately at The Harley Street Clinic and Barts Heart Centre, St. Bartholomew's, and also serves NHS patients at University College Hospitals. Dr Segal is renowned for his patient-centred approach in treating heart rhythm disorders.

    Graduating from King's College London in 1995, Dr Segal has dedicated his career to cardiology, specialising in cardiac electrophysiology. He completed his training at St. Mary's and St. George's Hospitals in London and further honed his expertise with a Fellowship in Electrophysiology & Devices at Prof George Klein's centre in Canada in 2007. His research in mapping complex ventricular arrhythmias earned him a doctorate from The National Heart & Lung Institute, Imperial College in 2008.

    Dr Segal treats a wide range of conditions, including atrial fibrillation, SVT, ectopics, and ventricular tachycardia. He performs procedures such as catheter ablation, pacemaker implantation, and the fitting of Implantable Cardioverter Defibrillators (ICDs). His work aims to improve patients' quality of life by addressing heart rhythm issues.

    In addition to his clinical practice, Dr Segal is actively involved in research and publishes regularly in cardiology and electrophysiology journals. He is the lead for electrophysiology and arrhythmias at UCLH and a member of the European Heart Rhythm Association Exam Setting Committee. His professional memberships include the Royal College of Physicians, the British Heart Rhythm Society, and the Heart Rhythm Society (USA).
