摘要： Systems and methods acquire electrocardiograms using a first electrode associated with a region of heart tissue and a second body surface electrode. An analog or digital processing element is coupled to the first and second electrodes for conditioning the first electrode to emit a pacing signal and for conditioning the second electrode to sense paced electrocardiograms occurring as a result of the pacing signal. The systems and methods also employ a template of an electrocardiogram of a cardiac event of known diagnosis; for example an arrhythmia that the physician seeks to treat. The systems and methods compare this event-specific template to a sample of a paced electrocardiogram. 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.

摘要： Systems and methods for heating body tissue place a multi-function structure having an exterior wall in contact with body tissue. The structure includes an array of electrically conducting electrode segments carried by the exterior wall. An electrically conductive network is coupled to the electrode segments, including at least one electrically conductive path individually coupled to each electrode segment. The systems and methods operate in a first mode during which the network is electrically conditioned to individually sense at each electrode segment local electrical events in tissue, such as electrical potentials, resistivity, or impedance. The systems and methods operate in a second mode during which the network is electrically conditioned, based at least in part upon local electrical events sensed by the electrode segments, to couple at least two electrode segments together to simultaneously transmit electrical energy to heat or ablate a region of body tissue.

摘要： Systems and methods analyze biopotential morphologies in myocardial tissue by comparing a template of a cardiac event of known diagnosis to one or more samples of a paced cardiac event. The systems and methods generate an output based upon the comparison. The comparison yields an output, which indicates how alike the input sample is to the input template. The output can be used by the physician, for example, to aid in the location of sites that are potentially appropriate for ablation. The systems and methods employing different pacing and/or comparative techniques to provide multiple outputs. The pacing techniques that the systems and methods employ can comprise entrainment pacing or pace mapping. Various alternative comparison techniques include matched filtering, cross correlation, norm of the difference, and symmetry matching.

摘要： Analog or digital systems and methods filter an artifact from a composite signal, which comprises sample values arranged with respect to time. The systems and methods select sets of WL sample values in time-sequence along the composite signal and arrange the WL sample values of each set into ordered positions following a predetermined permutation. The systems and methods select one of the ordered positions, z, within each permutation. The systems and methods generate a filter output comprising the sample values occupying the ordered position, z, of each permutation in time-sequence with the composite signal. The systems and methods remove artifacts from signals derived from a biological event; for example, electrograms, electrocardiograms, electroencephalograms, electrogastrograms, electromyograms, and respiratory signals.

摘要： Electrode assemblies and associated systems employ a nonporous wall having an exterior for contacting tissue. The exterior peripherally surrounds an interior area. The wall is essentially free of electrically conductive material. The wall is adapted to assume an expanded geometry having a first maximum diameter and a collapsed geometry having a second maximum diameter less than the first maximum diameter. The assemblies and systems include a lumen that conveys a medium containing ions into the interior area. An element free of physical contact with the wall couples the medium within the interior area to a source of electrical energy to enable ionic transport of electrical energy from the source through the medium to the wall for capacitive coupling to tissue contacting the exterior of the wall.

摘要： Systems and methods identify the physical, mechanical, and functional attributes of multiple electrode arrays. The systems and methods provide a structure adapted for contact with tissue in an interior body region. The structure possesses a physical property affecting tissue contact. The systems and methods include an identification code that uniquely identifies the physical property of the structure, such as size of the structure, or shape of the structure, or symmetry or lack of symmetry of the structure, or a stiffness value of the structure, or combinations thereof. The systems and methods also include an identification element attached in association with the structure to retain the identification code. The identification element is adapted to provide an output representative of the identification code. The structure also carries at least one electrode. The electrode possesses-a physical property, or both. The identification code uniquely identifies both the physical property of the structure and the physical or functional property of the electrode. The identification element retains one or more of these physical or functional properties for output and consideration prior to use of the structure.
