| Abstract: | This paper proposes a detection method of ST segment change in real-time Electrocardiography(ECG) monitoring, which uses line-fitting to extract the baseline, uses wavelet transform to monitor QRS complex, and combines J+X method and T wave detection method to attain the feature point of ST segment.A ST segment recorded message is designed in real-time monitoring.Through a long period of standard database simulation and clinical tests, this method is proved to be accuracy and useful. |
