METHOD AND SYSTEM OF AUTOMATED HEMODYNAMICAL DETECTION OF ARRHYTHMIAS

摘要

A method for automated detection of arrhythmias in a patient is disclosed, said method comprising: obtaining continuous pressure data from a cardiac chamber of said patient; segmenting said pressure data to correspond to beat segments; extracting features from each of said beat segments with respect to a predetermined number of earlier beat segments, said features relating to at least some of the criteria selected from: beat-to-beat change in the duration of said beat segments, beat-to-beat change in the peak-to-peak amplitude of said beat segments, beat-to-beat change in heart rate of said patient and change in value and instance in time of max dP/dt, where P is pressure and t is time; and classifying each of said beat segments as ectopic or normal, wherein ectopic beat is determined using a set of predetermined rules aimed at detecting abnormality in features of each of said beat segments with reference to predetermined thresholds.
