Problems solved by technology

[0005] In daily life, the complexity of hemodynamics and pulsation rhythm changes in the cardiovascular system makes the pulse wave shape (spatial domain) and period (time domain) dynamically change in a large range, and the theoretical research on quantitative description of this change and The system is still lacking, resulting in the performance of the malignant arrhythmia identification and burst prediction method in practical application needs to be further improved and improved

Embodiment

[0096] Embodiments: The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0097] In this embodiment, the database is composed of fingertip photoplethysmography signals of healthy people, patients with extreme tachycardia and extreme bradycardia, among which 40 healthy people (20 young people: 21-34 years old, 20 elderly people) : 68-85 years old), 17 patients with extreme bradycardia and 23 patients with extreme tachycardia. The signal sampling frequency is 250Hz, and the length varies from 5 minutes to ...

Abstract

The invention discloses a system for judging age and health status and identifying malignant arrhythmia by a pulse signal time-space domain combination model. The system comprises the following steps:acquiring pulse signals at a vessel part of the body surface of a human body for a preset time length; performing pulse signal time-space resolution modeling; and performing malignant arrhythmia identification and outbreak prediction based on the parameters of the pulse time-space analytical model. The invention proposes use of the pulse time-space analytical model to quantitatively describe pulse signal periods and waveform change, can judge age and rhythm of the heart, and can realize intelligent identification of malignant arrhythmia and outbreak early warning.

Description

technical field [0001] The invention relates to the technical field of portable medical equipment, in particular to a system for judging age, health status and identifying malignant arrhythmia by combining pulse signal time and space with a model. Background technique [0002] Through the pulse signal we can get a lot of information, such as age, health status. Arrhythmia, especially malignant arrhythmia, is a cardiovascular disease that leads to syncope and even death. Statistics show that there are about 290 million patients with cardiovascular disease in my country, and 26.8% of them have cardiac arrhythmia. Malignant arrhythmias such as ventricular fibrillation or ventricular tachycardia have become the leading cause of death. However, my country's limited high-quality medical resources and uneven distribution of medical resources between eastern and western regions, urban and rural areas, lead to the mortality rate of cardiovascular disease patients in rural and outer ...
