Method of using spectral measures to distinguish among atrial fibrillation, atrial flutter and other cardiac rhythms

摘要

A method and apparatus are provided for differentiating among atrial-flutter, atrial-fibrillation and other cardiac rhythms. The method includes the steps of estimating a spectral entropy of atrial cardiac activity from an electrocardiogram of a patient and determining that the patient has atrial fibrillation when the spectral entropy is greater than a predetermined value.
