Dr Gwilym Morris – Cardiac Electrophysiologist and AF Ablation Specialist

Dr Gwilym Morris is a cardiologist and cardiac electrophysiologist with more than 15 years’ experience in the treatment of heart rhythm disorders. He performs a large number of cardiac ablations each year, with particular expertise in atrial fibrillation.

Dr Morris was one of the first electrophysiologists in Australia to use pulsed field ablation (PFA) for atrial fibrillation and among the first in the world to integrate PFA with Faraview, a next-generation cardiac mapping platform. His early adoption of new ablation technologies is complemented by extensive experience in established techniques, allowing the treatment approach to be tailored to each patient and their particular heart rhythm disorder.

His procedural practice also includes ablation for atrial flutter, supraventricular tachycardia and ventricular arrhythmias, together with pacemaker and defibrillator implantation.

He trained in medicine at the University of Oxford where he won prizes for academic achievement and research. After completing an intercalated degree in Physiology he was awarded a Wellcome Trust scholarship to fund a period of research before commencement of undergraduate clinical training.

His postgraduate medical and further cardiology training was undertaken in Manchester, UK. He advanced his skills in cardiac ablation and pacing through a prestigious clinical fellowship in pacing and cardiac electrophysiology at the world-leading cardiology department of the Royal Melbourne Hospital led by Professor Jonathan Kalman. During this fellowship, Dr Morris received intensive training in advanced arrhythmia management, cardiac ablation and pacing, and conducted research into mechanisms of atrial fibrillation.

Dr Morris’s research spans atrial fibrillation, sinus node disease and arrhythmias in athletes. His British Heart Foundation-funded PhD investigated sick sinus syndrome and gene therapy, with the work receiving the Heart Rhythm Society UK Young Investigator Award and the Turnberg Cup. He was subsequently awarded a major British Heart Foundation research grant to investigate strategies for improving atrial fibrillation ablation. He remains active in AF research, is widely published and has been invited to speak at meetings around the world.
