ATRIAL FIBRILLATION DETECTION

摘要

A method of detecting atrial fibrillation from an ECG is presented, comprising a combination of at least two of the steps of analyzing R-R interval sequences to produce a measure of the irregularity of the RR interval sequence; canceling the QRST portion of the ECG, and analyzing the resulting signal; and analyzing the ECG signal preceding the QRS complex, to determine the presence or absence of P-waves. This is followed by a step of using a classifier to classify the ECG into one of two classes, namely "AF present" and "AF absent", based on a range or ranges of results of the measurement steps which are determined in advance. The invention improves patient monitoring.
