Dr Dewi Thomas
Consultant Cardiologist and Electrophysiologist
MBChB (Edin), MD, MRCP, CCDS, ECES
I am a Consultant Cardiologist and Electrophysiologist at Morriston Hospital Regional Cardiac Centre and was appointed to this post in September 2016.
I specialise in all aspects of heart rhythm management including the use of catheter ablation to treat arrhythmia, bringing state-of-the-art experience to the ablation of complex atrial and ventricular arrhythmias. I also have a strong clinical and research background in the implantation and follow-up of pacemakers, defibrillators and resynchronisation devices, and hold international accreditation through both American and European heart rhythm societies in invasive electrophysiology and implantable device therapy.
I graduated from the University of Edinburgh in 2002, and undertook clinical training in Edinburgh and South Wales, completing subspecialty training modules in heart failure and heart rhythm management. In 2012 I was awarded a research doctorate (MD) by Cardiff University and in 2016 I completed an advanced clinical fellowship in electrophysiology at the James Cook University Hospital, Middlesbrough.
Some of the principal treatments carried out by Dr Dewi Thomas at Spire include:
COVID-19 testing or antibody tests are not available as a standalone service at Spire Cardiff Hospital.
