Dr David Gareth JonesBSc MBBS MD FRCP

Consultant Cardiologist


Dr David Gareth Jones read medicine at St Mary’s Hospital Medical School (now part of Imperial College London) and won prizes in anatomy and histology. He was awarded a BSc scholarship and subsequently obtained first class honours in the field of cardiovascular medicine in 1997.

After he graduated with his degree in medicine (MBBS) in 2000, Dr Jones trained in general internal medicine in London and Plymouth.

He subsequently trained in clinical cardiology, cardiac electrophysiology and cardiac devices at Greenlane in Auckland, New Zealand; and in London at Charing Cross, Hammersmith, Royal Brompton and Harefield hospitals.

His doctoral research (MD awarded 2013) was in the field of interventional electrophysiology in advanced heart disease. In particular he looked at the role of ablation therapy in managing patients with atrial fibrillation and heart failure.

Clinical expertise

Dr David Gareth Jones is a consultant cardiologist specialising in:

  • treatment of cardiac arrhythmias (heart rhythm abnormalities) such as atrial fibrillation and ventricular tachycardia
  • catheter ablation procedures
  • pacemaker and defibrillator implantation and follow-up
  • cardiac resynchronisation therapy (CRT)
  • left atrial appendage occlusion procedures.

He has extensive experience in medical and interventional management, including advanced mapping and ablation therapy, for all atrial and ventricular arrhythmias.

He has a specific interest in patients with arrhythmias and advanced heart failure, including arrhythmia management and catheter ablation in patients who have had heart or lung transplants.

Research interests

His clinical research interests include arrhythmias in patients with advanced heart disease, including heart failure and post-transplantation. His MD(res) doctoral thesis, awarded in 2013, examined the role of catheter ablation to treat persistent atrial fibrillation in patients with heart failure.


He regularly teaches cardiology trainees, electrophysiology fellows and cardiac physiologists, and runs simulator-based training at Harefield.

He is clinical lead for the catheter laboratory emergencies training programme, using the CRRISiS® (Clinical Risk Reduction in Simulated Settings) model developed with Harefield Hospital’s STaR centre in order to improve patient safety and quality of care.


Dr David Gareth Jones has published and presented widely in the fields of cardiac electrophysiology and devices, including in the sub-specialist area of congenital heart disease and cardiac transplantation. He introduced and teaches ultrasound guidance for pacemaker procedures at the Trust, and together with colleagues has introduced high-density substrate mapping to facilitate procedures to treat atrial fibrillation and ventricular tachycardia.


Dr Jones became a Member of the Royal College of Physicians (MRCP) in 2003, and was awarded the Fellowship of the Royal College of Physicians in 2017.

He holds full European Heart Rhythm Association (EHRA) accreditation in both Interventional Cardiac Electrophysiology and Cardiac Pacing/ICDs.
