Dr Dewi Thomas is a Consultant Cardiologist and Electrophysiologist at Morriston Hospital Regional Cardiac Centre and was appointed in September 2016.

He graduated from the University of Edinburgh in 2002, and completed junior doctor training in Edinburgh and South Wales. In 2012 he was awarded a research doctorate (MD) by Cardiff University, and in 2016 he completed an advanced clinical fellowship in Electrophysiology at the James Cook University Hospital, Middlesbrough.

He specialises in all aspects of heart rhythm management including the use of catheter ablation to treat arrhythmias such as Atrial Fibrillation, SVT and Ventricular Tachycardia. Since his appointment he’s helped lead the expansion and development of ablation services in the region, resulting in Morriston becoming the highest volume EP centre in the country.

Cardiac Electrophysiology is also devoted to the implantation and follow-up of pacemakers, defibrillators and resynchronisation devices and he has a strong clinical and research background in this area too. During his fellowship training he worked as part of a team to deliver the UK’s first leadless ultrasound-based pacemaker, and more recently he established Wales’ first Conduction system pacing programme.

The other area of medicine that’s very important to him is education, and he’s heavily involved in medical education on a local and national level. He is a senior lecturer and clinical lead for cardiovascular medicine at Swansea University Medical School, and represents Wales on the British Heart Rhythm Society’s education committee where he has been helping to set the national accreditation exams for the last 6 years. This work compliments his clinical activities and he hopes it enhances his ability to explain and promote understanding during patient interactions.

He holds international accreditation through British, American and European heart rhythm societies, in invasive electrophysiology and implantable device therapy. He has been extensively published in peer reviewed journals and regularly invited to speak at national and international meetings
