Method and apparatus for predicting the efficacy of cardioversion

摘要

An apparatus and method for predicting the efficacy of cardioversion as a modality for reverting a patient with atrial fibrillation to normal sinus rhythm. Blood flow through the patient's atrium is measured, converted and processed using nonlinear or chaotic processing to obtain a differential radius signal. The number of excursions of the differential radius beyond a threshold value indicates whether cardioversion will be successful.
