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

[0095] Embodiment: The technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiment is only a part of the embodiment of the application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0096] In this embodiment, the database is composed of fingertip photoplethysmogram signals of healthy people, patients with extreme tachycardia and patients with extreme bradycardia, among them, 40 healthy people (20 young people: 21-34 years old, 20 old 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 ranges from 5 minutes to 66 minutes.

Abstract

The invention discloses a system for judging age, health status and malignant arrhythmia by combining time and space domain models of pulse signals. Malignant arrhythmia identification and burst prediction of spatiotemporal analytical model parameters. The invention proposes to quantitatively describe the changes of pulse signal period and waveform by adopting the pulse spatiotemporal analysis model, which can judge age and heart rhythm, and can realize intelligent identification and sudden warning of malignant arrhythmia.

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 malignant arrhythmia by combining time and space domains of pulse signals with models. Background technique [0002] Through the pulse signal, we can get a lot of information, such as age and health status. Arrhythmia, especially malignant arrhythmia is a cardiovascular disease that can lead to fainting or even death in patients. Statistics show that there are approximately 290 million patients with cardiovascular disease in my country, and 26.8% of them suffer from cardiac arrhythmia. Malignant arrhythmias such as ventricular fibrillation or ventricular tachycardia have become the primary cause of death in patients. However, my country's high-quality medical resources are limited, and the uneven distribution of medical resources between the east and the west, as well as between urban and rural areas, has resulted in...
