    • Systems and methods analyze biopotential morphologies in body tissue. The systems and methods use a template of a biopotential event of known cause in body tissue. The template comprises a plot of variations in biopotentials over time and not a spacial distribution of endocardial surface activation. The systems and methods compare this template to a sample of a biopotential event externally triggered in body tissue. The sample comprises a plot of variations in biopotentials over time and not a spacial distribution of endocardial surface activation. The systems and methods generate an output based upon the comparison. The systems and methods can be used to compare an event-specific template of a cardiac event of known diagnosis to a sample of a paced cardiac event. The comparison yields a matching factor indicating how alike the input sample is to the input template. The systems and methods compare the matching factor to a predetermined value to determine the location of sites that are potentially appropriate for ablation. A matching factor that indicates close similarity between the sample and the template suggests that the pacing site lies close to a region potentially appropriate for ablation to treat the arrhythmia.
    • 系统和方法分析身体组织中的生物电位形态。 系统和方法使用身体组织中已知原因的生物潜在事件的模板。 该模板包括随时间的生物电势的变化图,而不是心内膜表面活化的空间分布。 系统和方法将该模板与身体组织中外部触发的生物潜在事件的样本进行比较。 样品包括生物电势随时间变化的图,而不是心内膜表面活化的空间分布。 系统和方法基于比较产生输出。 系统和方法可用于将已知诊断的心脏事件的事件特定模板与起搏心脏事件的样本进行比较。 比较产生一个匹配因子,表明输入样本与输入模板的相似度。 系统和方法将匹配因子与预定值进行比较,以确定潜在适合于消融的部位的位置。 表明样品和模板之间密切相似的匹配因子表明,起搏部位靠近可能适合消融治疗心律失常的区域。

    • Systems and methods use an array of multiple electrodes supported for operative association with a region of heart tissue, in tandem with a roving second electrode supported for movement relative to the multiple electrode means for operative association with selected, different regions of endocardial tissue within the heart. An analog or digital processing element conditions one of the multiple electrodes and the roving electrode to emit a pacing signal while the other one of the multiple electrodes and the roving electrode records paced electrograms occurring as a result of the pacing signal. A processing element and method input a template of a cardiac event of known diagnosis sensed using the array of multiple electrodes. The processing element and method inputs a sample of a cardiac event acquired by pacing from at least one roving electrode and sensed with the array of multiple electrodes. The processing element and method electronically compare the input sample to the input template and generates an output based upon the comparison. The output can aid the physician in locating potentially appropriate sites for ablation.
    • 系统和方法使用多个电极的阵列,其被支撑用于与心脏组织的区域操作性关联,与被支撑用于相对于多个电极装置移动的粗纱第二电极串联,以与心脏内心脏组织的选定的不同区域有效结合 。 模拟或数字处理元件调节多个电极和粗纱电极之一以发出起搏信号,而多个电极和粗纱电极中的另一个记录起搏电迹作为起搏信号的结果。 处理元件和方法输入使用多个电极阵列感测的已知诊断的心脏事件的模板。 处理元件和方法输入通过起搏从至少一个粗纱电极获取的心脏事件的样本,并用多个电极的阵列感测。 处理元件和方法将输入样本与输入模板进行电子比较,并根据比较生成输出。 输出可以帮助医生定位潜在的适当的消融部位。
