Dr Sabine ErnstMD FESC

Consultant cardiologist, Reader in cardiology at Imperial College London


Dr Sabine Ernst qualified in medicine in Germany then continued her training in Los Angeles and Boston, USA, and in Switzerland.

Dr Ernst was director of a magnetic navigation laboratory in Hamburg, Germany.

In 2007, she moved to London, became a specialist in cardiology, and joined Royal Brompton and Harefield hospitals.

She is the research lead in electrophysiology at the Trust. Since 2012, she has been a Reader at Imperial College London.

Clinical expertise

Dr Ernst is a consultant cardiologist and a cardiac electrophysiologist with specialist expertise in treating:

  • catheter ablation of complex arrhythmias
  • atrial fibrillation
  • ventricular arrhythmia in both paediatric and adult patients
  • ablation with low or zero fluoroscopy
  • remote magnetic navigation.

Dr Ernst is one of the pioneers of remote magnetic navigation and catheter ablation without the use of x-ray. She has established these technique from its initiation to it becoming a routine clinical procedure using state-of-the-art equipment, including advanced 3D-mapping techniques. The technique of remote magnetic navigation can particularly benefit patients with congenital heart disease, complex anatomy and arrhythmias. These types of patients form a major part of Dr Ernst’s clinical work.

Research interests

Recently, Dr Ernst’s research has focused on novel imaging techniques to visualise the autonomic nervous system. This aims to better understand the nervous system’s role in the development and management of cardiac arrhythmias.


Dr Ernst has published extensively in the field of cardiac electrophysiology and catheter ablation.

Together with Professor Yen Ho, Dr Sabine Ernst published a book entitled Anatomy for Cardiac Electrophysiologists, which is now also available in Chinese.

Dr Ernst serves on the editorial board of a number of scientific journals, including:

  • Europace
  • Journal of Interventional Cardiovascular Electrophysiology
  • Herzschrittmacher + Elektrophysiologie [German]
  • Circulation: Arrhythmia and Electrophysiology.

Since 2013, she has been associate editor of Heart, an international peer-reviewed journal.


Dr Ernst is a Reader in Cardiology at Imperial College London.

She is a highly regarded speaker on innovation and technology at national and international conferences. She lectures on these subjects each year at the European Society of Cardiology’s annual congress.

Dr Ernst also regularly organises courses within the Trust and abroad. She actively collaborates with researchers in US, Canada, Europe and Asia.
