Abstract (in Japanese) (See Japanese page) 
(in English) Multielectrode cardiac mapping is used for clarifying myocardial activation sequences in an experimental study for cardiac arrhythmias or even in such a clinical examination. To visualize the activation propagation as an isochronal map or movie, the determination in manual of a series of activation time in every electrode is indispensable, however it is an extremely hard work, and moreover it is often difficult to be executed objectively and accurately, especially in visualizing the complicated arrhythmias such as atrial fibrillation. We developed a new algorithm to automatically visualize the activation propagation from the multielectrode mapping data. Utilizing this algorithm enabled us to clearly visualize even the complicated propagation, and also to clearly visualize the abnormal conduction, which becomes an important clue for clarifying the arrhythmia mechanisms. Clinically, this algorithm might possibly help the ablation therapy by quick identification of the origin of the arrhythmias.
