Portable cardiovascular function detection system based on pulse wave

Based on the pulse wave, a portable cardiovascular function detection system is designed, realizing the synchronous measurement of brachial artery pulse wave and blood pressure, and calculating a number of cardiovascular parameters based on the characteristic points of the pulse wave waveform and the blood pressure value. The system integrates data collection, processing, display, and report query, which is compact and easy to carry. Through comparative experiments with the SphygmoCor pulse wave analysis system, the correlation coefficient r of multiple cardiovascular parameters is greater than 0.79, and the p value is less than 0.01, indicating that the system has high detection accuracy.
