阅读说明：本技术 用于映射心律异常的方法和系统 (Method and system for mapping cardiac rhythm abnormalities ) 是由 马尔科姆·芬利 肖莱·霍纳尔巴卡什 理查德·席林 罗斯·亨特 瓦康斯·乌拉 于 2019-04-23 设计创作，主要内容包括：一种计算机实现的方法和系统,用于使用从多个电极记录的电描记图数据识别负责支持或引发异常心律的心肌的一个或多个区域；该方法包括以下步骤：将记录时间段划分为若干个分析时间段,并且将每个感测位置与所定义的测地线距离内的多个其他的感测位置配对；对于分析时间段中的每一个,定义每个激活信号针对每个配对内的每个位置的相对定时,在相应分析时间段内针对每个电描记图激活定义对的前导信号；以及将一系列前导信号分数分配给每个电描记图配对；在变更分析时间段的同时,在相同的位置处重复分析至少一次；组合针对每个信号位置的每个分析时间段,以提供每个信号位置相对于所定义的测地线区域内的其他位置倾向于前导的比例的统计度量,以及关联来自重叠的区域的前导信号分数,以提供相对组合的前导信号分数；从而提供指示,所述指示是对每个感测位置通常在其它区域之前的相对可能性的指示。(A computer-implemented method and system for identifying one or more regions of the myocardium responsible for supporting or inducing abnormal heart rhythms using electrogram data recorded from a plurality of electrodes; the method comprises the following steps: dividing the recording time period into a number of analysis time periods and pairing each sensing location with a plurality of other sensing locations within the defined geodesic distance; for each of the analysis time periods, defining a relative timing of each activation signal for each location within each pair, activating a preamble signal of the defined pair for each electrogram within the respective analysis time period; and assigning a series of preamble signal scores to each electrogram pair; repeating the analysis at least once at the same location while varying the analysis time period; combining each analysis time period for each signal position to provide a statistical measure of the proportion of each signal position that is prone to preamble relative to other positions within the defined geodesic region, and correlating preamble scores from overlapping regions to provide a relative combined preamble score; thereby providing an indication of the relative likelihood that each sensed location is generally ahead of other areas.)
