Electrophysiology – Mats Jensen-Urstad group

The group's research area is within electrophysiology. The group is responsible for Scandinavia's largest electrophysiological unit, which together with an extensive database offers excellent possibilities for research in the field. The main focus of the research is currently on techniques in catheter ablation.

Our research

An important clinical outcome of the present research is the development of cryoablation, ie ablation through freezing, where the group is now internationally the frontline in the field. The result of which has led to that more patients are now being able to receive curative treatment of their heart rhythm disorders parallel to minimal risk of complications.

The research group further studies how structural changes of the myocardium affect treatment outcome and prognosis in patients with arrhythmias such as atrial fibrillation and ventricular tachycardias.

Another area of research is on how genetic factors may play a role in changes in the myocardium and the results of treatment for arrhythmias.

The group is part of the Heart and Lung Diseases Unit at the Department of Medicine, Huddinge (MedH).
