Image personalized heartComputer Model of a personalized heart

In cooperation with the IANM (KIT) and the IEKM (University Heart Center Freiburg), researchers at IBT proposed an electro-mechanically coupled computer model of a personalized human heart. The manuscript was published in the Journal Mathematics.

BildTransit Time Measurement in Indicator Dilution Curves

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 .

Image graphical abstractNumber of cameras for the 3D reconstruction

Researchers at IBT investigated how many cameras are needed so that a microsurgical operating channel can be reconstructed as completely as possible in 3D.
The work was published in the Journal of Imaging (MDPI):

EHRA Congress 2021

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”.

CombinationsEstimation of Atrial Fibrosis with the ECG

Researchers at IBT investigated whether the amount of diseased fibrotic tissue in the atria can be estimated non-invasively and quantitatively with features extracted from P waves of the 12-lead ECG.
The work was published in the Journal of Clinical Medicine (MDPI).

BildNon invasive prediction of atrial fibrillation driver location

IBT researcher Giorgio Luongo and colleagues presented a machine learning-based classification of 12-lead ECG to discriminate between patients with pulmonary vein drivers vs. those with extra-pulmonary vein drivers of atrial fibrillation.
The paper is published in the Cardiovascular Digital Health Journal.

Transmembrane potentialProtocol to Assess Arrhythmia Vulnerability

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.

Bild Herzmodellierung 2021Computational hearts for success of therapy

KIT's Institute of Biomedical Engineering develops, based on mathematical equations, a computational heart model to enable targeted therapy of cardiac arrhythmias. The model supports medical research and development in the fields of diagnostic and therapeutic approaches.
