Professor Schilling established the arrhythmia research program at St Bartholomew’s Hospital. Barts was one of the first centres to carry out randomised clinical trials investigating interventional treatment of cardiac arrhythmia and has developed and validated techniques for using novel technological applications like 3D image integration into mapping systems for the treatment of arrhythmia. These innovations have reduced radiation exposure and improved success rates for patients.

He has a busy clinical practice specialising in interventional ablation for complex arrhythmia.

He was one of the team that led the successful merger of the Heart Hospital and Barts trust cardiovascular units to form the biggest cardiovascular centre in the UK.

He now serves as the clinical director for strategy and commercial for Barts Hospital is responsible for a team of strategic project leaders and the private practice team at Barts Hospital.

He is the medical director for the Arrhythmia Alliance and the Atrial Fibrillation association, two international charities supporting patients with heart rhythm problems through education and influencing government policy.
