Abstract

The invention discloses a measuring method and a measuring device for pulse wave propagation time. The method comprises: synchronously collecting a pulse wave signal and an electrocardiogram signal ofa measured person, extracting characteristic points of the pulse wave signal and the electrocardiogram signal, and calculates a pulse conduction time PAT. The pre-ejection PEP was calculated according to the electrocardiogram signal. The pulse wave propagation time (PTT) is obtained by subtracting the pre-ejection PEP from the calculated pulse propagation time (PAT). The invention eliminates theinfluence of the pre-ejection period and improves the measurement accuracy of the pulse wave propagation time PTT.

Description

technical field [0001] The present application relates to the technical field of human physiological signal measurement, in particular to a pulse translation time (pulse translation time, PTT) measurement method and measurement equipment. Background technique [0002] Cardiovascular disease refers to the occurrence of pathological changes in the heart and blood vessels, including coronary heart disease, arteriosclerosis, arrhythmia, hypertension, etc. With the development of society and economy, great changes have taken place in the national lifestyle, especially the aging of the population and the acceleration of urbanization, which will cause a significant increase in the risk factors of cardiovascular diseases, leading to a continuous increase in the number of cardiovascular diseases . According to the statistics of the World Health Organization, millions of people die from cardiovascular diseases every year in the world, among which in China, more than 5 million people ...
