Electrocardio collecting system and device and computer-readable storage medium

Abstract

The invention discloses an electrocardio collecting system and device and a computer-readable storage medium. The system includes an electrocardio collecting module, a type analysis module, a data compression module and a decompression module. Collection of electrocardio signals is achieved, and a sampling sequence is generated; corresponding type information is judged according to the electrocardio signals; the sampling sequence is obtained, by utilizing a measurement matrix corresponding to the type information and the sampling sequence, electrocardio measurement signals are generated; by utilizing the measurement matrix, a dictionary matrix corresponding to the type information and the electrocardio measurement signals, sparse signals are obtained, and by utilizing the sparse signals and the dictionary matrix, an electrocardio signal sequence is obtained. The corresponding measurement matrix is selected according to the type information, the sampling sequence is compressed in a targeted mode through utilization of the measurement matrix, then the dictionary matrix and the measurement matrix are utilized to conduct decompression on the electrocardio measurement signals to obtainthe sparse signals, the integrity of data in a decompression process is ensured, the electrocardio signal sequence is obtained at last, and the signal quality of the electrocardio signals during compression and decompression is guaranteed.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to an electrocardiogram acquisition system, device and computer-readable storage medium. Background technique [0002] Electrocardiogram (ECG) is one of the most commonly used clinical examinations. It can help medical staff diagnose arrhythmia, myocardial ischemia, myocardial infarction and its location, and determine the impact of drugs or electrolytes on the heart. However, many serious heart diseases are sudden, such as most of the sudden death patients are outside the hospital. At the same time, some chronic heart diseases such as arrhythmia are sporadic, and some patients may not develop the disease in a short-term ECG examination, resulting in missed diagnosis. Therefore, the realization of long-term ECG collection will be beneficial to the diagnosis and treatment of heart diseases, and can effectively improve the survival rate of patients. [0003] At present, there are se...

Problems solved by technology

However, since the acquisition of ECG signals requires a high sampling rate, directly storing and sending the original ECG signals will face the problems of excessive data volume and insufficient transmission speed.

However, the method of compressing the ECG signal based on the principle of compression before storing and sending it may lead to a decrease in the quality of the ECG signal or even damage it, which will have a serious impact on the doctor's diagnosis
