2022 Satellite Event

This year's CEI satellite meeting will be held on September 8th in Tampere Finland, following Computing in Cardiology 2022. This event will focus on bringing together the experts and leaders from across the world to share their progress and challenges in researching and implementing ECGI. For more information on this event and the program, visit the CEI-organized events page.

CEI 2022 Seminar Series


We are very excited to announce the third series of presentations in the Consortium for ECGI 2022 Seminar Series. The topic of this seminar will be arrhythmogenesis and its relation to ECGI. With this seminar series, we hope to organize presentations from leaders in the field of cardiac electrophysiological and modelling thereof.


See the archive page for more information on the past seminars, and stay tuned for the upcoming seminars!


New seminar Info:


On September 14th, 2022, 16:00 pm -- 17:00 pm CEST (15:00 -16:00 BST/8:00 – 9:00 MST).

Dr. Ruben Coronel, Amsterdam University Medical Center, Amsterdam, The Netherlands.

Title: “Challenging non-invasive electrocardiographic imaging: Combined activation and repolarization mapping to identify and destroy the arrhythmogenic substrate”.

Abstract: “The initiation of reentrant ventricular arrhythmias depends on the temporal and spatial concurrence of a substrate and a trigger. Preventive treatment is often aiming to pharmacologically or anatomically altering the arrhythmogenic substrate. Ablative procedures require the identification of the susceptible tissue(s) by invasive activation mapping of the reentrant pathway. This is not always possible, because the induced arrhythmia is not the same as the clinically significant arrhythmia, is not monomorphic, is not sustained or is not hemodynamically tolerated. In these cases, the target (‘border zone’) tissue is defined morphologically (by imaging techniques and electroanatomical mapping) during a paced rhythm. An alternative functional method to identify the susceptible arrhythmogenic substrate by combined activation/repolarization mapping without the need to induce the arrhythmia will be presented. Non-invasive electrocardiographic imaging allows combined activation and repolarization mapping and may thus support the localization of the susceptible tissue and guide its subsequent destruction.”

Dr. Michele Orini, University College London and Barts Heart Centre, London, United Kingdom.

Title: “ECG-Imaging, validation and delineation of substrate for ventricular tachycardia”.

Abstract: “In this talk, I will present our work focusing on using ECG imaging for clinical applications. These include validation studies conducted analysing data collected during electrophysiological studies for ventricular tachycardia ablation as well as studies for cardiac conditions (e.g. Arrhythmogenic Right Ventricular Cardiomyopathy, cardiac amyloidosis etc). We report on agreement with invasive electro-anatomical mapping parameters (activation, repolarization, ventricular tachycardia exit sites, scar delineation, etc) as well as on ECGI integration with structural parameters from cardiac magnetic resonance imaging.”

Do you also wonder what the effect is of differences in segmentations and segmentation programs on the inverse problem of electrocardiography? Within the Model Building working group of the Consortium for ECG imaging, we try to answer this question and with that we need your help!

Four imaging datasets were selected and thereof already several people segmented the heart (endocardium and epicardium), lungs and thorax, wherefore we are very grateful! However, more segmentations are required and therefore we want to ask for your help.

Each dataset contains its own challenge, like imaging artifacts or segmentation without contrast. On the Google Drive, the four datasets are uploaded as nrrd and DICOM files:

1. Dalhousie: segmentation of blood pools, epicardium/endocardium, lungs and thorax.

2. P43: segmentation of blood pools, epicardium/endocardium, lungs and thorax, challenge with imaging artifacts.

3. Nijmegen: segmentation of blood pools, epicardium/endocardium, lungs and thorax

4. Auckland: segmentation of epicardium, lungs and thorax, challenge with imaging artifacts and without blood pool contrast.

If you are in the opportunity to segment one or more of these datasets using the images uploaded at the drive with your own segmentation tools before the 10th of February, it would really help us making another step forward in the analysis towards answering our question! Thanks in advance for your help and for the segmentations, we really appreciate it! If you have any questions, don’t hesitate to ask me (Machteld, m.j.boo...@umcutrecht.nl)!

We have a new EDGAR dataset for you all to use! RV and LV pacing, sinus rhythm, induced LBBB, all recorded using a torso tank and epicardial sock array. Thanks to Laura Bear, and IHU LIRYC for providing this dataset. Go check it out here: http://edgar.sci.utah.edu/torso-tank/25-bdx-160620-exp16.html
