Dynamic electrocardiogram all-channel pacemaking pulse detection device and method

Abstract

The invention provides a dynamic electrocardiogram all-channel pacemaking pulse detection device and method. The device comprises a controller, a program control tri-state isolator, a program controlfrequency controller, a program control electrocardiograph simulation front end, a USB controller and a data storage device. According to the method based on the device, a high-frequency sampling bi-directional separation technology serves as a core, after being completely separated from electrocardiogram signals of the human body, pacemaking pulse signals on all leads are processed independently,exhaustive detection of the pacemaking pulse signals is achieved, the characteristics of the pacemaking pulse signals and the characteristics of the electrocardiogram signals of the human body are reliably and truly reflected respectively, and the problem that high-frequency signals and low-frequency signals are mutually interfered is solved completely; meanwhile, the data storage efficiency of apacemaking electrocardiogram is improved, and the portable, power-saving and quick application requirements of a dynamic electrocardiogram system are met.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a dynamic electrocardiogram full-channel pacing pulse detection device and a method thereof. Background technique [0002] With the economic development of society and the continuous improvement of material and cultural living standards, the average life expectancy in the world has increased to 71.4 years, and the average life expectancy in my country has increased from 45 years in 1949 to 76.1 years in 2016. The growth of life expectancy is basically the concentrated expression of the development and progress of human science and technology, especially medicine and medical technology. From years of statistical data, people can clearly understand that cardiovascular disease is the most serious factor threatening human life, especially the degradation or loss of heart function resulting in bradycardia or heart function conduction disorders, severe cases wil...

Problems solved by technology

[0005] Using the dynamic electrocardiogram system to monitor patients wearing pacemakers not only records the routine electrocardiogram activity, but also records the pacing pulse signal when the pacemaker is working, only in this way can it reflect the pacing and sensing performance of the pacemaker Whether it is normal or not, and whether its working parameters need to be adjusted; however, due to the mutual constraints of its portable, internal power supply, embedded system control, real-time storage, and post-transmission characteristics, the dynamic electrocardiogram has not been able to realize the pacemaker since it was produced. Full lead complete monitoring and recovery of pacing pulses

The initial dynamic ECG sampling rate was 75Hz, and later developed to 125Hz. The current conventional sampling rate is 250Hz and 500Hz. From the perspective of completely restoring the signal, this can fully meet the collection requirements of the human body's autonomous ECG, and can completely restore the ECG. signal; however, for the pacing pulse sent by the pacemaker, such a sampling rate basically cannot effectively sample it

Therefore, according to the needs, 500Hz, 4KHz or even 10KHz single-channel and dual-channel pacing product version recorders appear in the dynamic electrocardiogram system, which indeed improves the detection rate of pacing pulses, but it still cannot fully meet clinical needs.

The main problems are: first, because it uses single-channel or dual-channel sampling, in clinical applications, it often encounters the problem of interference in individual leads or lead electrodes falling off, which ultimately results in the inability to collect effective ECG data , especially the pacing pulse signal data, which leads to the failure of clinical monitoring and effective analysis; second, even if the signal data is collected, because the data does not distinguish the pacing pulse signal and the ECG signal of the body, the two signals are not digitized In the process of processing, there is a phenomenon of mutual interference, which cannot truly reflect the completely real working conditions of the pacing ECG.

A series of problems such as the transmission, processing, storage, and power consumption of a large amount of data brought about by this have prominent contradictions with the portability, power saving, and fastness of dynamic electrocardiograms.
