Catheter ablation is the key therapy in treating arrhythmia. For this treatment planning, 3D electroanatomical map is used to find the origin but it needs the direct access to heart with electrode and requires the experience and long time to get detailed information. So if the origin can be predicted with CT image and ECG data before treatment, it improves the quality of treatment. This paper propose the model to predict catheter ablation origin from 12-lead ECG + position of electrodes and CT image.
