Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0023] like figure 1 The shown myocardial work index monitoring system based on cardiac shock signal includes a circuit processing module 2, a signal digital processing module 3 and a signal analysis module 4;

[0024] The circuit processing module 2 is used to convert the body vibration optical signal brought by the human heart beat into the corresponding body vibration electrical signal, and perform zero-phase filtering on the body vibration electrical signal, remove the DC signal, and retain the AC signal containing the vibration information. , and amplify the preset multiple of the AC signal containing vibration information;

[0025] The signal digital processing module 3 is used to adopt the Butterworth low-pass filter of the former item and the latter item (the former item refers to the first Butterworth filtering of the origin...

Abstract

The invention discloses a heart shock signal-based myocardial work index monitoring system, which comprises a heart shock signal sensing module, a circuit processing module, a signal digital processing module and a signal analysis module.The heart shock signal-based myocardial work index monitoring system combines practical application requirements, designs a convenient acquisition module, effectively removes interference components in signals through signal processing, and improves the accuracy of heart shock signal processing. And finally, relevant parameters required for calculating the myocardial work-doing index are extracted through medical verification, so that the requirements of telemedicine can be met, the heart abnormity can be early warned in time, and the method has important significance on early heart function abnormity early warning.

Description

technical field [0001] The invention relates to the technical field of monitoring of human vital signs, in particular to a myocardial work index monitoring system and method based on cardiac shock signals. Background technique [0002] At present, cardiovascular disease has become the number one killer that threatens human health. Early prevention, early diagnosis and early treatment of cardiovascular disease are one of the most concerned issues in the medical field. Therefore, daily real-time monitoring of cardiac function is of great significance. Monitoring finds problems and intervenes in time to stifle cardiovascular disease in its infancy, which greatly reduces the difficulty of treatment and improves the quality of life of patients with prognosis. [0003] Myocardial work index (Tei index), also known as myocardial comprehensive index, was first proposed by medical scientist Chuwa Tei. It refers to the ratio of the sum of ventricular isovolumic contraction time (ICT...
