About Dr. Oliver Segal

With 12 years’ experience as a Consultant Cardiologist & Electrophysiologist (an expert in heart rhythm disorders) in London teaching hospitals (including at the largest arrhythmia centre in Europe) and 9 years as a medico-legal expert, Dr Segal combines knowledge and breadth of experience based on high case volumes and procedural technologies to produce objective, incisive reports on a range of electrophysiological / heart rhythm related injuries from life-threatening to minor, from complications of catheter ablation and pacemakers, to atrial fibrillation to anti-arrhythmic drugs, Wolff-Parkinson-White Syndrome to lead fracture, and cardiac rhythm device system infection to left atrial appendage occlusion devices.

I now work full time in the private sector at The Harley Street Clinic. I was a Consultant Cardiologist & Electrophysiologist in the NHS at University College London Hospital and then Barts Heart Centre, St. Bartholomew’s Hospital between 2008-2026. Having been appointed as an NHS Consultant in 2008, I was made a Fellow of the Royal College of Physicians and of the Heart Rhythm Society (USA) in 2013.

My experience since 2009 includes provision of reports to many solicitors, the ABMU Health Board, Wales, a London Borough Council and the MedicalDefence Union.
