Dr Segal is a leading cardiologist based in London specialising in Atrial Fibrillation and Heart Rhythm Disorders, and an acknowledged expert in Catheter Ablation. He is internationally recognised for his expertise in Electrophysiology and use of advanced techniques involved in implanting pacemakers, defibrillators, biventricular pacemakers / ICDs and left atrial appendage occlusion devices.
Dr Oliver Segal qualified from King's College Hospital, London in 1995 and trained in cardiac electrophysiology and device implantation at St Mary's and St George's Hospitals in London. In 2004 he won 1st prize in the prestigious Heart Rhythm Society Young Investigator Award for Clinical Research in San Francisco, USA for his work on ventricular tachycardia which he undertook at the National Heart & Lung Institute, Imperial College, London. He was then selected for and completed a fellowship in Pacing and Electrophysiology at Professor George Klein's world famous laboratory in London, Ontario, Canada
Dr Segal is a Consultant Cardiologist at The Heart Hospital, University College London Hospital and The Harley Street Clinic hospitals, London. He has been practising electrophysiology for 10 years, and has performed over 1500 ablations and over 800 device implantation procedures, including pacemakers, defibrillators (ICDs), biventricular pacemakers and left atrial appendage occlusion devices (Watchman). He has published widely on all aspects of arrhythmias and has presented his work at numerous national and international conferences. His special interests include atrial fibrillation, ventricular tachycardia, ablation and cardiac resynchronisation therapy.
Dr Segal specialises in:
Atrial fibrillation (AF)
Atrial fibrillation is the commonest heart rhythm disorder in the developed world and is the leading cause of stroke in younger people and can sometimes cause heart failure. AF results from abnormal electrical impulses in the atria, which can lead to rapid, irregular palpitations, breathlessness, chest pain, light-headedness or tiredness.
Drugs are often ineffective but it can often be cured with a procedure called catheter ablation, performed as a keyhole procedure with patients needing only one night in hospital. Dr Segal is an expert in performing catheter ablation for atrial fibrillation
Catheter Ablation - The most important invention in cardiology
From the perspective of arrhythmia, I think the most important invention in cardiology in the last 50 years is the invention of catheter ablation. Since its inception it has since progressed at an astounding rate so we can now potentially treat (and often cure) almost every single cardiac arrhythmia using keyhole techniques with patients going home the same or the following day. I know how much of a difference this has made to the quality of life of my patients.
Latest blood thinning drugs and cardiac devices
We now have access to remarkable drugs for the prevention of stroke in patients with AF. AF is the second leading cause of stroke and sadly strokes which occur due to AF are more likely to be disabling or fatal. Unlike the traditional drug warfarin, the new drugs, or novel oral anticoagulants (NOACs) don't need blood test monitoring, have very few interactions with food or other drugs and most importantly cause much less bleeding in the brain. My patients are all benefiting from these new alternatives.
There are now new pacemakers which are so small they are implanted completely inside one of the heart's chambers rather than needing a long lead to connect to a battery under the collar bone. They are inserted by keyhole via the leg, leaving only a tiny scar. It is thought this will mean fewer pacemaker-related infections and avoids the issue of leads breaking in the future. When the battery runs out, another small device is implanted next to the old one. Dr Segal is an expert at implanting pacemakers, defibrillators, cardiac resynchronisation devices and the Watchman device.
The Expert Guide to Preparing for a Cardiology Consultation
There is alot of innacurate or outdated cardiology information on the internet, which means that without an expert guide, doing your own research can be more confusing than helpful. As Dr Segal says, "Visits to a cardiologist are often the most important event in a person’s life at that time". It is therefore vital to ensure that you are properly prepared and know which questions to ask in order to ensure that you receive the best possible care. See Cardiologist Consultation Checklist
