本文首先对单导联心电图（ Ｅ Ｃ Ｇ）信号的小波变换进行假设检验，得到 Ｑ Ｒ Ｓ波群的位置和检验的虚警漏报概率，然后对 １２ 导联检测结果作峰点比对融合和决策加权融合处理，最终得到精确的 Ｑ Ｒ Ｓ位置。实验表明这种方法对各种主要病症的 Ｑ Ｒ Ｓ波群均能准确检出，正确率在 ９９９５％ 以上。
In this paper, we first test the wavelet transform of single-lead electrocardiogram (E C G) signal to get the position of Q R S-wave group and the false alarm probability of false alarm. Then we make the peak-to-peak fusion of 12-lead test results And decision-weighted fusion, and finally get the exact Q R S position. Experiments show that this method can accurately detect all kinds of QS waves in various major diseases with the correct rate above 99.95%.
