DETERMINING DEVICE AND MAPPING SYSTEM FOR ORIGIN OF ARRHYTHMIA

A determination device (100) for determining the origin of an arrhythmia and a mapping system (200) are disclosed. In the determination device (100), an analysis unit (120) is configured to process ECG data extracted over a predetermined period of time by a data extracting unit (110) and input the processed data into a determination model (131), where a calculation is performed thereon to produce origin information about the origin. An output unit (140) is configured to output the origin information, and a model configuration unit (130) is configured to configure the determination model (131). The determination device (100) allows identifying a cardiac site suitable for focused mapping, thereby dispensing with the need to map the whole heart and shortening the time required for mapping. The mapping system (200) includes the determination device (100). With the origin information about the arrhythmia's origin, a physician can know a cardiac site corresponding to the origin of the arrhythmia in a timely manner before or during a procedure. This can reduce the time required for mapping and result in an enhancement in surgical efficiency.
