Mechanisms of Atrial Fibrillation and their Implications for Treatment

Place: IBT library, building 30.33, room 517

Welcome to the home page of the Institute of Biomedical Engineering at Karlsruhe Institute of Technology (KIT). Since more than 50 years we do research and teaching in the field of Biomedical Engineering.

In interdisciplinary projects together with medical doctors and medical industries we investigate new technical systems, that help to diagnose diseases earlier and more accurate and that make therapies more successful.

Main focus of the research program of Prof. Dr. Olaf Doessel is the analysis of biosignals from the heart (ECG and electrograms), the imaging of electrophysiological sources in the heart (ECG Imaging), computer modelling of the heart and numerical field calculation in human body.

A second focus is currently established by Prof. Dr. Werner Nahm: it’s the research on optical systems in medicine and life sciences, e.g. new intraoperative applications of Optical Coherence Tomography (OCT) and confocal microscopy in neurosurgery.

Influence of filtering on the ST segment in the ECG

The so-called ST segment in the ECG plays an important role with the diagnosis of myocardial infarction. In a recent published study, the influence of different filtering methods on the ST segment in the ECG was analyzed. Realistic, simulated ECGs with a region of infarction und known noise were used for evaluation. It became apparent, that methods can influence the ST segment in such a manner that the diagnostic information can be falsified.

Valuable Information Regarding the Interpretation of the Atrial ECG Published

December/23/2016
IBT scientists in collaboration with cardiologists from Lund, Sweden identified mechanisms contributing to the ECG of the atria (P-wave). Results regarding the limited contribution of the left atrium and the influence of the site of earliest activation were published in the renowned journal "Europace“ of the European Society of Cardiology (ESC).

Paper about the Mapping using Basket Catheters published

Basket-type catheters allow to acquired simultaneous electrograms from many distributed atrial positions. Correct interpretation of the mapping data, however, is complicated by the deformation of the catheter. We quantitatively analyzed both in-silico and clinical data from panoramic basket catheter mapping in our open-access publication „Basket-Type Catheters: Diagnostic Pitfalls caused by Deformation and Limited Coverage“. Results emphasize that knowledge about the electrode positions during mapping is required for correct interpretation of panoramic mapping data.

IBT strongly represented at the annual meeting of the German Society for Biomedical Engineering

October/6/2016
With 19 participants and 17 scientific contributions, the IBT was one of the strongest groups at the annual meeting of the German Society for Biomedical Engineering (DGBMT). This year’s meeting was held together with the Austrian and Swiss societies in Basel, CH (D-A-CH). Furthermore, Robin Andlauer and Joachim Greiner did win the first and second prize in the student competition.
