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].



IBT presents at SPIE Photonic West 2019

At the international conference SPIE Photonic West in San Francisco, CA, USA Andreas Wachter presents his currents results. The paper "Development of a real-time virtual reality environment for visualization of fully digital microscope datasets” was presented during the poster session.

Biophysical Society Meeting
IBT presents at Biophysical Society Meeting

Recent IBT research was presented at the 63rd Annual Meeting of the Biophysical Society in Baltimore, MD, USA. Die work "Sinus Bradycardia Due to Electrolyte Changes as a Potential Pathomechanism of Sudden Cardiac Death in Hemodialysis Patients“ was featured with an Early Career Scientist Travel Award and well received in the poster session.

IBT represented at Honorable Reception of the President

Axel Loewe was credited during the Honorable Reception of the KIT president for his success in the Gips-Schüle junior scientist award. Around 80 invited guests experienced a 3 hour program together with a gala dinner in the casino of KIT campus north. Besides the presentation of the KIT doctoral prizes, those KIT members who won important prizes and grants were honored.

Estimating the personal risk for atrial flutter

Researchers at IBT in collaboration with clinicians from Städtisches Klinikum Karlsruhe have developed a method to estimate an individual’s risk to suffer from atrial flutter using computational models. The novel method has lately been published in the journal „Frontiers in Physiology“ and allows to identify all pathways along which atrial flutter can be sustained in a personalized model of the patient. In this way, the effect of therapeutic interventions like catheter ablation or drugs can be assessed in advance.

Pollnow Promotion
PhD graduation Stefan Pollnow

Stefan Pollnow defended his PhD thesis „Characterizing Cardiac Electrophysiology during Radiofrequency Ablation - An Integrative Ex vivo, In silico, and In vivo Approach“ on December 13 and passed the exam with distinction. We congratulate warmly!

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.
