12-lead Ecg Signal Processing System Based On Digital Ecg Cable

ECG is an important gist to diagnose the cardiovascular disease and estimate the cardiovascular function in modern iatrology. The electrocardiograph is an instrument to make ECG examination. On the one hand,it can display, print and analysis ECG. On the other hand, It can make examination on the body without hurting. So it is used widely in the hospitals and other medical organizations. At present, in our country, the cardiovascular disease has a high incidence and it is very dangerous as well. Especialy in the undeveloped district where the medcial level is not very high, the cardiovascular disease can reasult in death mostly. Because the cardiovascular disease can be prevented and controled by making ECG examination, the electrocardiograph is used widely.The 12-lead electrocardiograph based on the digital ECG lead is designed. The ECG digital lead is a new design. Comparing with the old one, it can convert the analog ECG data to digital data by itself , so that it can not only link with the electrocardiograph but also the PC. It is a precondition for PC to examin the ECG directly.The article introduces the soft design of the digital ECG lead and how to deal with the digital ECG signal. The content includes the following item: the design of the digital ECG lead, the technique of the ECG signal fliter, how to analyze the digital ECG signal and the way of arrhythmia diagnoses,, the digital ECG lead is a innovation.The article introduces its function, characteristic and soft design detailedly. The ECG data filter and analysis of ECG signal all adopt the WT (Wavelet Transform) technique.The WT (Wavelet Transform) technique is illuminated in this article .At last, the article introdues how to diagnose the arrhythmia.The 12-lead electrocardiograph based on the digital ECG lead will be used widely. The technique of the ECG signal analysis is already a focus. And the digital ECG lead will be developed better in future.
