This paper aims to present a very-large-scale integration (VLSI) friendly electrocardiogram (ECG) QRS detector for body sensor networks. Baseline wandering and background noise are removed from original ECG signal by mathematical morphological method. The performance of the algorithm is evaluated with...
空间特征提取:卷积神经网络(CNN)在空间上具有强大的特征提取能力,能够从心电信号中提取出不同导联的时域和频域特征。这些特征可以帮助模型识别和区分不同类型的心电波形,如P波、QRS波群、T波等。 时间动态特征捕捉:长短期记忆网络(LSTM)在时间序列数据中能够捕捉到长期依赖关系,对信号的时间动态特征进行建模。在心电信...
心电图(ECG)分析九步法 1、Rhythm -节律:分析心电图的节律,即心跳的规律性。 2、Rate -心率:计算每分钟心跳的次数。 3、P waves - P波:观察P波,它代表心房的电活动。 4、PR interval - PR间期:测量从P波开始到QRS波开始的时间,反映心房到心室的传导时间。 5、QRS complex - QRS波:它代表心室的电活动...

If the axis is more negative than –30° it is referred to as left axis deviation. The axis is calculated (to the nearest degree) by the ECG machine. The axis can also be approximated manually by judging the net direction of the QRS complex in leads I and II. The following rules ...

The diagnosis of RVH is often difficult to establish as the QRS complexprimarily represents depolarization of the left ventricle, which has afar greater myocardial mass compared with the right ventricle. Hence,the finding of ...
This research is based on an ECG biometrics system which segments the QRS-complex, extracts the non-fiducial features and sends the data to a two-level classifier. For spectral analysis, the discrete Fourier transform (DFT), and discrete cosine transform (DCT) were used to transform the signal...
Load and plot an ECG waveform where the R peaks of the QRS complex have been annotated by two or more cardiologists. The ECG data and annotations are taken from the MIT-BIH Arrhythmia Database. The data are sampled at 360 Hz. loadmit200figure plot(tm,ecgsig) holdonplot(tm(ann),ecgsi...
