摘要
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.
