Workshop "Integrated Heart Model"


Engineering for Health

Welcome to the web page of the Institute of Biomedical Engineering (IBT) at Karlsruhe Institute of Technology (KIT). For more than 50 years we have been active in research and teaching in the field of biomedical engineering.

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

The main focus of the research program of Prof. Dr. Olaf Dössel is the analysis of biosignals from the heart (ECG and electrograms), the imaging of electrophysiological sources in the heart (ECG imaging). Moreover, we are working on impedance tomography for lung perfusion and hypothermia in stroke patients [more].

The area of research of Prof. Dr. Werner Nahm's group is optical systems in medicine and life sciences. Current projects are focussing on surgical visualization and optical diagnosis [more].

The group of Dr. Axel Loewe develops computational models of the heart and applies them to cardiological problems. We focus on cardiac electrophysiology and elastomechanics to contribute to answer clinical questions such as the genesis of e.g. cardiac arrhythmias and appropriate treatment strategies [more].

Influence of left atrial size on the ECG

How does left atrial size affect the electrocardiogram (ECG)? If a robust recognition of left atrial enlargement would be possible using only the ECG, physicians would be provided with a cheap means to identify an important predictor for atrial fibrillation. In an effort to answer this question, scientists of the IBT have designed and performed a study to virtually enlarge the left atrium and simulate the corresponding ECG. Results of this study show how different types and degrees of left atrial enlargement influence the ECG and how they could potentially be detected in clinical practice. A particularly interesting results is that the frequently used clinical marker „PTF-V1“ is rather an indicator for a thicker atrial wall than for an enlarged atrium.

IBT presents at r2b-student techpitch

Convincing the audience in 180 seconds – scientists and founders presented their ideas and concepts during the r2b-student techpitch on Nov, 15. Afterwards, interested students could get in touch with the researchers to discuss about potential thesis projects.

DGBMT 2018
IBT strongly represented at the Conference of the Society of Biomedical Engineering 2018 in Aachen

The annual conference of the Society of Biomedical Engineering (DGBMT) 2018 took place in Aachen.
Among a lot of scientific contributions, the IBT was represented with 16 contributions and was one of the strongest groups at the annual conference. Furthermore, Armin Müller and Tamara Wirth won the 7th and 8th prize in the student competition of the DGBMT.

Campus Report podcast features IBT

A step towards personalized medicine and more effective treatments that’s what computer simulation of atrial fibrillation promise. The Computational Cardiac Modeling group at the Institute of Biomedical Engineering of KIT works towards a mathematical formulation of the heart’s function and its realistic representation in computational models. The head of the group, Dr. Axel Loewe, reports about the work in this week’s Campus Report podcast.

Preis Patientensicherheit
Patient Safety Award

IBT scientists Axel Loewe and Olaf Dössel won the Patient Safety Award (2nd place) together with clinical collaborators from University Heart Center Freiburg-Bad Krozingen. The honored study introduces two novel ECG-based approaches for real-time assessment of success of catheter ablation to terminate perimitral flutter. Perimitral flutter is an atrial arrhythmia, which occurs frequently subsequent to ablation for atrial fibrillation. The methods were thoroughly evaluated using medical engineering simulations and put to test in a clinical study comprising a validation cohort. In the future, the methods can be implemented in clinical mapping devices. The suggested measures to assess success of ablation have great potential to significantly increase patient safety through shorter invasive procedures as well as higher success rates and therefore a smaller number of redo procedures.

New research assistant at IBT

We welcome Miss Deborah Nairn as a research assistant starting October 2018. Her research will focus on identifying low voltage areas to guide atrial fibrillation therapy. This consists of identifying the relationship between bipolar voltage during sinus rhythm and ongoing AF. She aims to develop a robust method to pinpoint diseased tissue based on bipolar voltage taking into consideration different confounding factors.  
Miss Nairn completed her bachelor’s degree in Mathematics at the University of Aberdeen and Master’s degree in Data Science for Decision Making at Maastricht University. Her research topics focused on comparing state of the art ECG T-wave detection algorithms and building a signal-based dynamic model to detect ischemia and describe the progression over time.
