Dr David Gareth Jones

Consultant cardiologist, Cath Lab director at Harefield Hospital
Specialises in catheter ablation procedures, pacemaker and defibrillators, and cardiac resynchronisation therapy (CR).

Dr David Gareth Jones is a consultant cardiologist and is the cath lab (catheterisation laboratory) director at Harefield Hospital.

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

He then 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) was in the field of interventional electrophysiology in advanced heart disease. He looked at the role of ablation therapy in managing patients with atrial fibrillation and heart failure.

Dr Jones’s interest in rhythm and extends beyond medicine – he is a keen violinist and has played with the European Doctors Orchestra.

Clinical expertise

Dr David Gareth Jones specialises 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).

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

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

Research interests

Dr Jones’s 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 patient with heart failure.


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

In addition, he is the 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.

He is also the regional lead for EP (electrophysiology) training at the Royal Society of Medicine.
