Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After fusion of the T1 CMR scan and the ECG electrodes a model-based bidomain FEM is used for a step-wise measurement of the local activation times (resting potential: 290 mV; plateau: 0 mV; acceleration time: 3 ms) both Ende- and epicardially.
