摘要
Devices, systems, and methods for localizing and/or treating arrhythmias of a patient's heart, which are particularly useful for localizing focal atrial fibrillation, allow locating arrhythmogenic regions of a chamber of the heart using heart cycle signals measured from a body surface of the patient. Non-invasive localization of the ectopic origin or exit site allows focal, circular, and/or perimeter treatment to be directed so as to inhibit complex arrhythmias without having to rely on wide-spread and time consuming sequential searches and/or on massively invasive simultaneous electrocardial sensors. The invention recognizes that effective localization of these complex arrhythmias can be significantly enhanced by techniques and structures which separate heart cycle signals originating from differing chambers and/or regions of the heart tissue.
