Apparatus for frequency analysis of atrial fibrillation

摘要

An apparatus for frequency analysis of atrial fibrillation, as a measure of the state of the illness which includes a device for registration of electrical signals from the heart of a patient, a device for separating a signal originating from the atrium and a device for frequency analysis of the atrial signal. Preferably, the separating device has a system for identification of signals originating from the ventricles, a system for classification of the ventricular signals, a system for formation of the average of the classified ventricular signals and a system for subtracting the averaged, classified ventricular signals from the total registered signal, in order to obtain the atrial signal. Preferably, the registration device comprises electrodes to be placed on the patient and for simultaneous registration of conventional ECG signals.
