摘要： A cryoballoon control device (2), catheter system and temperature display method are disclosed. The control device (2) acquires a plurality of balloon circumference temperature values obtained by circumference temperature sensors (4) circumferentially disposed on a cryoballoon (1) and a balloon center temperature value obtained from a center temperature sensor (5) disposed at a center of the cryoballoon (1) and, automatically adjusts a flow rate of a coolant introduced into the cryoballoon (1) based on a comparison between a preset balloon temperature value and a comparative temperature value, to enable a temperature adjustment to the cryoballoon (1), wherein the comparative temperature value is the balloon center temperature value, any one of the balloon circumference temperature values, or a computational temperature value derived by a predefined algorithm from the plurality of balloon circumference temperature values. The cryoballoon catheter system is configured to display, on the display device (3), a plurality of balloon circumference temperature representation graphs surrounding a balloon center temperature representation graph, wherein when one of the balloon circumference temperature values exceeds a first predetermined threshold range, a corresponding one of the balloon circumference temperature representation graphs indicates a first alert condition which prompts an operator to adjust temperature of the cryoballoon (1).

摘要： 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.

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： An ablation lesion assessment method and system for obtaining ablation information by analyzing an intracardiac electrode signal from an ablation lesion are disclosed. The ablation lesion assessment system includes: a baseline calculation unit for generating a baseline for a signal profile and calculating a proportion of portions of the signal profile located above the baseline in the whole signal profile; a waveform comparison unit for obtaining a waveform comparison result by comparing the signal profile with an ablation pattern; and a determining unit for making a determination based on the proportion and the waveform comparison result and outputting the ablation information that indicates whether complete ablation has been achieved. The ablation lesion assessment method can utilize the ablation lesion assessment system to obtain the ablation information that indicates whether complete ablation has been achieved. This allows a surgeon to more easily know in real time during a cardiac radiofrequency ablation procedure, such as PVI, the progress in ablation or transmurality, thus making it possible to obtain a higher success rate and increased safety of the cardiac radiofrequency ablation procedure.

摘要： An ablation system and a nerve detection device thereof. The nerve detection device includes a power supply module (10), a computation and control module (20), an energy generation module (30) and a blood pressure monitoring module (40). The computation and control module (20) is electrically connected to both the energy generation module (30) and the blood pressure monitoring module (40). The energy generation module (30) is configured to connect to a detecting catheter (50) and to detect a given site in an artery by outputting first energy to the detecting catheter (50). The blood pressure monitoring module (40) is configured to connect to a blood pressure sensor (60). The blood pressure sensor (60) is configured to monitor a patient's blood pressure prior to and during the detecting of the given site by the energy generation module (30) with the first energy and to output the blood pressure monitoring result. The blood pressure monitoring module (40) is further configured to transmit the blood pressure monitoring result to the computation and control module (20). The computation and control module (20) is configured to determine, based on the blood pressure monitoring result, whether there is an ablation target at the given site. The detecting allows accurate location of an ablation target in an ablation procedure, which results in improved effectiveness and safety of the ablation procedure.
