Dr. Glyn Thomas is an award-winning Consultant Cardiologist and Electrophysiologist at the Bristol Heart Institute. He trained at University College London Medical School and worked in various London teaching hospitals before returning to university to begin research into the causes of abnormal heart rhythms. After gaining his doctorate from Cambridge University in 2006 he returned to London to sub-specialise in heart rhythm treatment at St Bartholomew's Hospital.
Dr. Thomas was appointed as Consultant Cardiologist & Cardiac Electrophysiologist at the Bristol Heart Institute in 2009. He has a special interest in treating heart rhythm problems such as atrial fibrillation and performs several hundred ablation procedures per year. He practises a patient-centred approach, ensuring individuals needs are understood and anxieties accommodated, incorporating an understanding of patient's lifestyles into his treatment plan. He recognises the importance of non-pharmacological treatments such as diet and exercise. He has a wealth of experience in the cardiac aspects of Dysautonomia including Postural Orthostatic Tachycardia Syndrome (POTS) and increasingly, the post-viral, multisystem disorder known as 'Long COVID'.
Dr. Thomas is a Fellow of the American College of Cardiology and has also written two books, Cardiology in Focus (Churchill Livingstone, 2004) and Ready Reference: Cardiology (Elsevier 2010). He has over 100 publications in scientific press specifically relating to the mechanisms and treatment of cardiac arrhythmias, and is a regular contributor to popular media.
In addition to Cardiology, he has a special interest in Critical Care Medicine.

He is now a full-time Critical Care Doctor with Great Western Air Ambulance Charity, respoding to medical emergencies/accidents across the South West by helicopter or rapid response car.

We found Dr Thomas very professional, friendly and with a good sense of humour. Having discussed my long term problems with recurring AF, Dr Thomas explained in easy to understand language his plans for my future treatment.
Glyn has an excellent bedside manner and is an excellent clinician.
Very positive. Punctual. Patient. Professional. I remembered to bring medical history notes that I had from recent hospital admissions which turned out to be useful.
Dr Thomas was excellent—very knowledgeable, thorough and professional. He explained my results clearly and was incredibly helpful, supportive and reassuring. Thank you.
A kind, and very approachable Doctor. He applied his specialty to my individual requirements, leaving me feel in very safe hands. I feel very fortunate to have found a Cardiologist that listened to what I said, took my opinions in to consideration, and is very supportive in methods to change my lifestyle. I feel I’m in the best of care, which brings me such relief and peace.
Dr Glyn Thomas was so kind and helpful. I’ve struggled for months to find a cardiologist that would listen to me as I was consistently dismissed purely because of my age. He listened to my symptoms, and my struggles, and explain what was happening and why with clear communication. He instantly put me at ease, and the reassurance I got from my appointment is incredible. I would genuinely recommend him to anybody with cardiology problems.
It was a real pleasure to meet Glyn and to get his advice on my heart issues. His manner inspired confidence and reassured me greatly about what my treatment will be. His explanation of the possible treatment was very clear.
Really professional and friendly with a great sense of humour. Gave very clear explanations of the treatment and allowed time for my questions. It was such a positive experience.
I was pleased to have been referred to Dr Glyn Thomas for my procedure. The care at the hospital as well as his medical professionalism were all I could have wished for.
I was referred by my Cardiologist to see Dr Thomas for a catheter ablation procedure. The outcome of my consultation with Dr Thomas was very positive and I am now waiting for the operation to take place. I was particularly pleased by the down to earth approach from Dr Thomas, who answered all of my questions. I am now quite excited and looking forward to the day the the ablation will take place. Regards David P.
Dr Thomas is a great colleague and companionate doctor. He is an expert in the field of cardiac arrhythmias and electrophysiology and I would highly recommend.
