A joint study of the University Heart Center Freiburg-Bad Krozingen and the IBT is featured on the cover page of the December issue of the renowned scientific journal "EP Europace". The study uses the ECG and ECGI to diagnose pathological changes in the atria.

The graduations season continues at IBT. We are very proud to announce that Mark Nothstein has successfully defended his PhD thesis: "Characterizing Atrial Fibrillation Substrate by Electrogram and Restitution Analysis”. Look what a nice hat his colleagues have made for him!

IBT researchers in the MY-ATRIA consortium have published a new method to better characterize atrial flutter. The approach makes use of graph-theoretical methods.

20 employees and students of IBT attended this year's annual meeting of the German society of biomedical engineering. 9 presentations and 3 posters from the three research groups were held and presented. Congratulations to Giorgio Luongo for winning the 2nd price for patient safety and to Hannes Welle for the 2nd place in the student competition.

Claudia Nagel presented her work at the workshop for Statistical Atlases and Computational Modeling of the Heart (STACOM). In her presentation, she talked about an application of the bi-atrial statistical shape model developed at IBT for identifying left atrial enlargement with the 12-lead ECG.

Let's congratulate our colleague Giorgio Luongo and the whole team for winning the second prize for the patient safety in biomedical engineering 2021 with the publication “Machine learning enables noninvasive prediction of atrial fibrillation driver location and acute pulmonary vein ablation success using the 12-lead ECG”. The award was handed in occasion of the BMT 21 conference in Hannover, and offered by the German Society of Biomedical Engineering (DGBMT).

IBT researchers have published an improved ventricular coordinate system for localization, data mapping and regression on cardiac geometries. An open MATLAB implementation of the method for precise and intuitive description of position in the heart is available for the community.
To the article

Claudia Nagel, Steffen Schuler, Olaf Dössel and Axel Loewe published a paper on a bi-atrial statisical shape model. The model includes the anatomical shape variations of the atria in the study population and was analyzed with standard evaluation criteria. The shape model and 100 exemplary atrial geometries suitable for electrophysiological simulations are openly available online.

Olaf Dössel, Giorgio Luongo, Claudia Nagel and Axel Loewe have written a review article that deals with the calculation of the ECG from computer models of the heart. Both the healthy heart and simulations of various heart diseases are considered. It becomes clear how computer modeling can contribute to a better interpretation of the EKG.

During the iHeart conference from July 1-3, about 200 participants virtually presented and discussed their research. The IBT was successfully involved with two presentations.

Congratulations to Jorge Patricio Sanchez Arciniegas on the completion of his PhD and the beginning of his work at IBT as a postdoc.

Researchers at IBT investigated how accurate a transit time measurement of an indicator bolus can be and proposed methods to enhance the accuracy. The work was published in the  Frontiers in Physiology .

A scientist of the IBT presented and discussed their research titled: “Spatial and Quantitative Assessment of the Correlation between Sinus Rhythm and Atrial Fibrillation Voltage Mapping to Identify Low Voltage Substrate in Persistent Atrial Fibrillation“ at this years EHRA congress. The congress was held online from the 23-25th of April, with this years' scientific program emphasising “Making connections to overcome arrhythmia”.

Der Workshop des IBT im Rahmen des Girls‘ Day 2021 traf auf großes Interesse des weiblichen Nachwuchses in den Bereichen Medizin und Technik.

Since April 1st, 2021 Dr. Marie Houillon is new research assistant in the computational cardiac modeling group at IBT.

Researchers at IBT showed the influence of the chosen protocol to induce arrhythmia on the assessment of atrial fibrillation vulnerability.

The paper was published in Frontiers of Physiology and is freely available.

IBT researches have published a paper, which presents a model-based method for solving an inverse problem of the heart biomechanics.

Nicolas Pilia defended his dissertation „Electrocardiogram Signal Analysis and Simulations for Non-Invasive Diagnosis - Model-Based and Data-Driven Approaches for the Estimation of Ionic Concentrations and Localization of Excitation Origins“ on February 18th 2021 and graduated with distinction. Congratulations!
