Noninvasive electrocardiographic imaging (ECGI) allows a non-invasive reconstruction of the electrical activation and recovery directly at the heart surface. This can yield important patient-specific insights about arrhythmia mechanisms and guide therapy, potentially improving clinical outcome. In this talk, I will present the implementation, validation and clinical application of ECGI in Maastricht. Furthermore, I will discuss our future plans for ECGI, which aim to integrate cardiac mechanics with cardiac electrical activity. This is essential to further our understanding of cardiac arrhythmogenesis. I will present (very) preliminary results of our collaboration with the SCI Institute and hope discuss our next steps with the audience.
