Systems and methods for analyzing biopotential morphologies in body tissue

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 systems and methods compare this template to a sample of a biopotential event externally triggered in body tissue. 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 coefficient indicating how alike the input sample is to the input template. The matching coefficient can be used by the physician, for example, to aid in the location of sites that are potentially appropriate for ablation.
