Dr David Gareth Jones

David Jones
Consultant cardiologist

Honorary clinical senior lecturer, Imperial
College London

Background and education

Dr David Gareth Jones read medicine at St Mary's Hospital Medical School (Imperial College, London), winning 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 graduating in 2000, Dr Jones trained in general internal medicine in London and Plymouth, obtaining his Membership of the Royal College of Physicians (MRCP) status in 2003.


Dr Jones subsequently trained in clinical cardiology and both cardiac electrophysiology and cardiac devices at Green Lane (Auckland, New Zealand), 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 the role of ablation therapy in managing patients with atrial fibrillation and heart failure. 


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

Areas of expertise

Dr Jones is a consultant cardiologist specialising in:

  • treatment of cardiac arrhythmias (heart rhythm abnormalities)
  • catheter ablation procedures
  • pacemaker/defibrillator implantation.


He also specialises in the management of all cardiac arrhythmias, including ablation of complex arrhythmias such as atrial fibrillation and ventricular tachycardia, as well as implantation of pacemakers, defibrillators and cardiac resynchronisation therapy (CRT). 


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.


He organises monthly training seminars for electrophysiology fellows and physiologists, and leads on simulator-based training in this speciality at Harefield. 

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