About Dr Oliver Segal

Dr Oliver Segal, Consultant Cardiologist and Electrophysiologist, currently works within the Bart's Heart Centre and University College Hospitals for his NHS patients. He sees patients in a private capacity at The Harley Street Clinic. He is highly specialised in a wide range of cardiac issues, with a specific focus on catheter ablations and devices to improve quality of life (AF catheter ablation, fitting pacemakers or devices such as an Implantable Cardioverter Defibrillator (ICDs)).

Dr Segal began his medical education at King's College London, graduating in 1995. He proceeded to train in cardiology within St. Mary's & St. George's Hospitals in London, before being awarded a Fellowship in Electrophysiology & Devices working alongside Prof George Klein in Canada. During his training, he also undertook a research degree focusing on mapping complex ventricular arrhythmias, which resulted in him being awarded a PhD from Imperial College for his work. He was also awarded the Young Investigator's Award by the Heart Rhythm Society for his PhD work.

Dr Segal continues to be an active researcher, publishing often in cardiology & electrophysiology journals with a keen focus on atrial fibrillation, catheter ablation and device implantation. He is also the lead within University College London Hospitals for electrophysiology & arrhythmias and sits on the European Heart Rhythm Association Exam Setting Committee.

Dr Segal dealt with my issue very swiftly and professionally. He was flexible about the type of appointment he offered..................face to face, Zoom or phone call. I had every confidence in him and I could feel that he wanted to find a solution for me, which he did.

The first interview over the internet is simply a money gathering excise. To charge the same fee as that charged for a face to face is not defendable or reflective of the standards of integrity I expect from practitioners of this level. The letter that follows simply restates the facts that do not merit a charge of£450 for 27 minutes. The next steps then advocated are those which could be asked for without this money harvesting exercise. I found it insulting.

Wow - shocked and dismayed to receive this and impossible to interpret without knowing who this is or what it refers to. Terms for service are very clearly laid out before seeing me, so there should be no surprises afterward. I treat all patient exactly the same and am dismayed to read that this is unjustified.

I have found Dr Segal to be an outstanding cardiologist/electrophysiologist and I’m grateful to be in his care. He completely replaced a pacemaker implanted poorly by another doctor and I have been feeling great in the six months since the revision. His expertise is evident in how he implanted the new pacemaker leads into the conductive pathway system, which has lead to improvements in my heart’s own structure and functioning.

My AF ablation and recovery went very smoothly, however the AF returned so Dr Segal performed a second ablation 6 weeks later, which was successful. Dr Segal kept me informed throughout and was a great help in making informed decisions about my treatment.

Dr Segal, was very thorough and made sure every part of my heart that needed to be looked at was. He ensured that it was all done on the day as I had travelled in. Then explained everything to me properly and made me feel at ease. Really pleasant and caring felling I got. Thank you
