【摘要】：心电图是心肌缺血、心肌梗塞等心血管疾病的首要检查项目之一,其ST-T段反映了心室复极的过程。利用小波变换的多分辨率分析对原始心电信号进行基线漂移校正和滤波,再结合凸点算子和动态搜索窗方法,对ST-T段定位。通过European ST-T数据库中的所有数据验证,该算法的平均识别率在93%以上。对于所有较为规律的心电信号,其识别率均高于90%。该方法避免了T波峰值定位难这一问题,有效地解决R波倒置、T波倒置和T波高尖等的定位。该算法计算的复杂度较低,能很好地嵌入到实际工程应用中。
[Abstract]:Electrocardiogram (ECG) is one of the most important examination items for cardiovascular diseases such as myocardial ischemia and myocardial infarction, and its ST-T segment reflects the process of ventricular repolarization. Combined with convex point operator and dynamic search window method, the ST-T segment is located. The average recognition rate of the algorithm is above 93% through all the data in the European ST-T database. For all the regular ECG signals, the average recognition rate of the algorithm is more than 93%. The recognition rate of the algorithm is higher than 90. This method avoids the problem of T wave peak localization and effectively solves the problem of R wave inversion T wave inversion and T wave height tip localization. The algorithm has lower computational complexity and can be embedded into practical engineering applications.
