Cardiac arrhythmia is an illness in which a heartbeat is erratic, either too slow or too rapid. It happens as a result of faulty electrical impulses that coordinate the heartbeats. Sudden cardiac death can occur as a result of certain serious arrhythmia disorders. As a result, the primary goal of electrocardiogram (ECG) investigation is to reliably perceive arrhythmias as life-threatening to provide a suitable therapy and save lives. ECG signals are waveforms that denote the electrical movement of the human heart (P, QRS, and T). The duration, structure, and distances between various peaks of each waveform are utilized to identify heart problems. The signals' autoregressive (AR) analysis is then used to obtain a specific selection of signal features, the parameters of the AR signal model. Groups of retrieved AR characteristics for three various ECG kinds are cleanly separated in the training dataset, providing high connection classification and heart problem diagnosis to each ECG signal within the training dataset. A new technique based on two-event-related moving averages (TERMAs) and fractional Fourier transform (FFT) algorithms is suggested to better evaluate ECG signals. This study could help researchers examine the current state-of-the-art approaches employed in the detection of arrhythmia situations. The characteristic of our suggested machine learning approach is cross-database training and testing with improved characteristics.
心律失常是一种心跳不规则的疾病,可能过快或过慢。它是由于协调心跳的电脉冲出现故障而发生的。某些严重的心律失常会导致心源性猝死。因此,心电图(ECG)检查的主要目的是可靠地检测出危及生命的心律失常,提供合适的治疗方法并拯救生命。心电图信号是表示人体心脏电活动的波形(P、QRS 和 T)。每个波形的各个峰值的持续时间、结构和距离都用于识别心脏问题。然后,对信号进行自回归(AR)分析,以获得信号特征的特定选择,即 AR 信号模型的参数。在训练数据集中,三组不同类型的 ECG 的检索 AR 特征被清晰地分开,为训练数据集中的每个 ECG 信号提供了高连接分类和心脏问题诊断。建议了一种基于两个事件相关移动平均值(TERMAs)和分数傅里叶变换(FFT)算法的新技术,以更好地评估 ECG 信号。这项研究可以帮助研究人员检查当前用于检测心律失常情况的最新方法。我们提出的机器学习方法的特点是跨数据库训练和测试,具有改进的特征。
