These recommendations are for information purposes only. Doctors providing recommendations do so in good faith and are not responsible for clinical outcomes.

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.

  • by Mr Neil Roberts, Cardiothoracic Surgeon

    I refer to this electrophysiologist based on my personal experience of his decision making, technical skill and knowledge base in this area. He is a true expert in this field, and is able to explain all the options available to patients and their families.

  • by Dr David Simcock, Respiratory Specialist

    Dr Oliver Segal is an excellent cardiologist. He provides a good service to his patients who speak highly of him. He is well supported by a multidisciplinary team and provides a high standard of all round cardiac care.

  • by Dr John Leach, Spine and Brain Surgery

    I have known Dr Segal for a numbers of years. As well as being a fantastic cardiologist he has a naturally relaxed and empathetic style which will help put you at ease. I highly recommend him.

  • by Dr Nigel Kellow, Pain Medicine Specialist

    Dr Segal is an excellent cardiologist and I highly recommend him both for routine cardiology and particularly for EP. I cannot think of anyone better for a pacemaker, ICD or an ablation.

  • byDr Garry Edward Savin, GP

    I recommend Oliver as an excellent doctor in his field. He has successfully helped several of my arrhythmia patients over the years.

  • by Dr Charlotte Manisty, Cardiologist

    Dr Segal is an expert in electrophysiology with an excellent approach to his patients.

  • About Dr Oliver Segal

    GMC number: 4209250

    Year qualified: 1995

    Place of primary qualification: University of London

    Dr Oliver Segal has over 15 years of experience in the management of arrhythmias, performing catheter ablation for atrial fibrillation (AF) and other arrhythmias, and implanting pacemakers, defibrillators and other cardiac devices. Appointed as a Consultant Cardiologist in the NHS at The Heart Hospital, University College London Hospitals in 2008, he moved to the Barts Heart Centre, St. Bartholomew's Hospital in April 2015. He focuses on seeing patients with rapid palpitations and tachycardias, irregular heartbeats, ectopic or 'skipped' beats, pauses and slow heart beats, dizzy spells and blackouts as well as patients with breathlessness and tiredness due to AF. He is an expert in performing electrophysiology studies, catheter ablation for all types of arrhythmia and implanting pacemakers, defibrillators (ICDs), loop recorders and biventricular pacing systems. He has performed over 1,900 electrophysiology studies and ablations (including the use of 3-dimensional and non-contact mapping systems) and over 1,000 device implantation procedures.

    Dr Segal graduated from King’s College London and King’s College Hospital, London in 1995. He trained in general cardiology at St. Bartholomew’s and The London Chest Hospitals. His specialist postgraduate training in cardiology and electrophysiology & device implantation was undertaken at St. Mary’s Hospital, The Heart Hospital (UCLH) and St. George’s Hospital in London. In 2007, he completed a fellowship in pacing and electrophysiology. For his research on mapping complex ventricular arrhythmias at The National Heart & Lung Institute, Imperial College, London, he was awarded his doctorate (MD) in 2008.
