    • 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 (1); 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 (7), beat-to-beat change in heart rate of said patient (7) 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 (10) 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 (9, 10).
    • 公开了一种用于自动检测患者心律失常的方法,所述方法包括:从所述患者的心室获取持续的压力数据; 分割所述压力数据以对应于节拍段(1); 从相对于预定数量的较早的拍子片段中的每个所述拍子片段提取特征,所述特征与选自以下的至少一些标准有关:所述节拍片段的持续时间中的节拍改变, 在所述节拍片段(7)的峰 - 峰幅度之间的节拍变化,所述患者(7)的心率的节拍变化和值的变化以及最大dP / dt的时间变化,其中P是 压力和t是时间; 并且将每个所述节拍片段(10)分类为异位或正常,其中使用一组预定规则来确定异位搏击,所述预定规则旨在参考预定阈值(9,10)来检测每个所述拍子片段的特征中的异常。
