    摘要: Disclosed relates to a method and an apparatus for analyzing an ECG signal, an electrophysiological signal recorder, a three-dimensional mapping system, and a computer device. The method includes: acquiring (S202) N first intracardiac electrical signals in a region of interest or at a reference point/in a reference region; generating (S204) a first comparison signal spectrogram according to the N first intracardiac waveforms; acquiring (S206) M second intracardiac electrical signals at the point of interest to acquire M second intracardiac waveforms; generating (S208) a second comparison signal spectrogram according to the M second intracardiac waveforms; performing (S210) a comparative analysis on the first comparison signal spectrogram and the second comparison signal spectrogram and generating a comparative analysis result; and outputting (S212) prompt information indicating whether the point of interest is a focal point according to the comparative analysis result. Accordingly, by performing spectrogram analysis on intracardiac electrical signals, and comparing and determining different spectrograms, the determination of the focal point can be more accurate, thereby providing the doctors with more effective information, such that the cure rate of arrhythmia diseases is effectively improved.

    摘要: The present disclosure relates to an image processing method and device, and a computer apparatus, a storage medium and a mapping system. An imageological image including a plurality of tomographic images is acquired. A three-dimensional reconstruction is performed according to the plurality of tomographic images to obtain a three-dimensional image model. The three-dimensional image model includes a three-dimensional myocardial fibrosis region image. A three-dimensional electroanatomic model including a three-dimensional abnormal myocardial tissue image is acquired. Since there is a certain correlation between an abnormal myocardial tissue region in the three-dimensional electroanatomic model and myocardial fibrosis, the three-dimensional image model and the three-dimensional electroanatomic model are registered, and an overlapping part of the three-dimensional myocardial fibrosis region image and the three-dimensional abnormal myocardial tissue image is determined as the location of a lesion. Therefore, the accurate positioning of a lesion location is realized, which effectively improves the surgery success rate.
