Professor Sabine Ernst | Royal Brompton & Harefield Hospitals Education

Professor Sabine Ernst

Consultant cardiologist and electrophysiologist
Specialises in the catheter ablation of complex arrhythmias using remote magnetic navigation.

Professor Sabine Ernst is a consultant cardiologist at Royal Brompton and Harefield hospitals.

Prior to this, she qualified in medicine in Germany then continued her training in Los Angeles and Boston, USA, and in Switzerland. She was the director of a magnetic navigation laboratory in Hamburg, Germany.

She later moved to London in 2007, became a specialist in cardiology, and joined Royal Brompton Hospital. She is the research lead in electrophysiology at the Trust and a reader at Imperial College London.

Clinical expertise

Professor Sabine Ernst has specialist expertise in treating:

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

Professor Ernst is one of the leaders of using remote magnetic navigation when performing cardiac ablation procedures. She has established this technique from its initiation to it becoming a routine clinical procedure using state-of-the-art equipment, including advanced three-dimensional mapping techniques.

Research interests

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.


Professor Ernst has published substantial amounts in the in the field of cardiac electrophysiology and catheter ablation.

Cooperatively with Professor Yen Ho, they have published a book entitled Anatomy for Cardiac Electrophysiologist, which is also available in Chinese.

Professor Ernst serves on the editorial board of several scientific journals, including:

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

Since 2013, she has been associated editor of Heart, and international peer-reviewed journal.


Professor Ernst is a reader in cardiology at Imperial College London.

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

In addition, Professor Ernst regularly organises courses within the Trust and abroad. She collaborates with researchers in US, Canada, Europe and Asia.
