Dr Oliver Segal

Consultant Cardiologist & Electrophysiologist

MBBS MD FRCP(London) FHRS

Specialty

Personal profile

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, The Heart and St. George’s Hospitals in London. In 2007 he completed a fellowship in pacing & electrophysiology at Prof. George Klein’s world-renowned electrophysiology unit in London, Ontario, Canada.

During his training, Dr Segal undertook a period of research on mapping complex ventricular arrhythmias at The National Heart & Lung Institute, Imperial College, London and was awarded his doctorate (MD) for this work in 2008. He presented part of that research at the 2004 Heart Rhythm Society in San Francisco, USA where he won 1st prize in the highly prestigious Young Investigator Award competition for clinical research.

Consultant Appointments

Dr. Segal was appointed as a Consultant Cardiologist in the NHS at The Heart Hospital, University College London Hospitals in 2008, moving to Barts Heart Centre, St. Bartholomew’s Hospital in April 2015 when services were transferred. He is lead for education and training in Electrophysiology and Programme Director for Overseas Fellows as well as lead for the Left Atrial Appendage Occlusion Device programme. He continues to hold an honorary contract at UCLH where he runs weekly arrhythmia clinics.

Dr Segal is a cardiologist who specializes in electrophysiology – the study of heart rhythm disorders. He focuses on seeing patients with rapid palpitations and tachycardia, irregular heart beats, ectopic or ‘skipped’ beats, pauses and slow heart beats, dizzy spells and blackouts as well as patients with breathlessness and tiredness due to atrial fibrillation. 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 1900 electrophysiology studies & ablations (including the use of 3-dimensional and non-contact mapping systems) and over 1000 device implantation procedures. He also performs pacemaker lead extraction and implants left atrial appendage occlusion devices (the Watchman & Amulet devices) for patients with AF and high risk of stroke who cannot take anticoagulants or when anticoagulants have failed.

Professional Memberships

  • Royal College of Physicians – Fellow

  • British Heart Rhythm Society - Member


Clinical Interests

Dr Segal’s clinical and research endeavours centre around atrial fibrillation ablation, mapping ventricular arrhythmias and diagnostics for SVT. He also has specialist interests in conduction disease in patients with myotonic dystrophy and the development of scoring systems to identify risk factors to guide cardiac device implantation in different patient groups. He presents and publishes widely on key aspects of cardiac arrhythmias and device implantation both nationally and internationally.
