Cardiology (heart)
Spoken Languages


Professor Sabine Ernst qualified in medicine in Germany but also continued her training in the USA (Los Angeles and Boston) and Switzerland. In 2007, she moved to London and became licenced as a cardiologist specialist. Before joining the Royal Brompton and Harefield NHS Foundation Trust, Professor Ernst was director of the magnetic navigation laboratory in Hamburg, Germany.

She holds the position of research lead in electrophysiology at Royal Brompton & Harefield NHS Foundation Trust and became Professor of Practice at Imperial College London in 2019.

Areas of expertise

Professor Ernst is a cardiac electrophysiologist with special expertise in: 

  • complex arrhythmias
  • atrial fibrillation
  • ventricular arrhythmia in both paediatric and adult patients. 

Professor Ernst is one of the pioneers of remote magnetic navigation. She has established this technique from its initiation to it becoming a clinical routine procedure using state-of-the-art equipment, including advanced 3D-mapping techniques. Patients with congenital heart disease, complex anatomy and arrhythmias especially benefit from this technique and form a major part of Professor Ernst's clinical work. 

More recently, Professor 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. 


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

She has published extensively in the field of cardiac electrophysiology and catheter ablation, and is a highly regarded speaker on innovation and technology at national and international conferences, lecturing on these subjects each year at the European Society of Cardiology’s annual congress. Professor Ernst also regularly organises courses within the Trust and abroad. 

Professor Ernst serves on the editorial board of a number of scientific journals, including Europace, the Journal of Interventional Cardiovascular Electrophysiology, Herzschrittmacher + Elektrophysiologie [German], and Circulation: Arrhythmia and Electrophysiology. 

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