  • 摘要: P, T波的检测在临床上是心血管疾病诊断的重要依据。由于其波形能量低、形态复杂,极易受到噪声干扰,导致现有检测算法精度仍有待提高。该文提出平稳和连续小波变换融合算法检测P, T波,利用连续小波变换的多尺度信息,获取心电图(ECG)信号中P, T波主要成分,融合其平稳小波对P, T波候选段进行平滑处理,消除波形中锯齿状毛刺对峰值点检测的影响,最后对P, T波过零点进行时移修正,保证过零点还原到原始信号过程中能够准确对应其峰值点,从而提高P, T波检测精度。该文算法在MIT-BIH arrhythmic数据库上进行验证,最终P波的误差率、敏感度、正确预测度达到:0.23%, 99.85%, 99.90%;T波的误差率、敏感度、正确预测度达到0.27%, 99.85%, 99.87%。
