In order to analyze the experimental cardiovascular signal with high accuracy,a system,integrating real-time monitoring and off-line further analysis,was developed and verified.The design,data processing and analysis methods as well as testing results are described.With 5 sampling frequency choices and 8channel data acquisition,the system achieved high performances in beat-to-beat monitoring,signal processing and analysis.Tests were carried out to validate its performance in real-time monitoring,effectiveness of digital filters,QRS and blood pressure detection reliability,and RR-interval timing accuracy.The QRS detection rate was at least 99.46% for the records with few noises from MIT-BIH arrhythmia database using the algorithm for real-time monitoring,and no less than 96.43% for the records with some noises.In the condition that noise amplitude levels were less than 80%,the standard deviations for RR-interval timing were less than 1 ms with a generated ECG corrupted with variousnoises from MIT-Bm Noise Stress Test Database.Besides,the system is open for function expansion to meet further studyspecific needs.
