An algorithm for evaluating the ECG signal quality in 12 lead ECG monitoring system

ECG signal quality is of great importance to real-time electrocardiogram(ECG) monitoring system. The paper introduces a new algorithm to evaluate the ECG signal quality. This algorithm is based on three features: heart rate score, spectral distribution ratio, and the variance between 12-lead ECG data. The result show that the proposed algorithm has a high Sensitivity of 95%, Specificity of 86.7%, and the Accuracy is 93.1%. The new algorithm is fast, accurate and reliable, showing strong potential to be applied in real-time ECG monitoring system.
