Objective: To judge whether the pulse rate variability can be used as a surrogate of heart rate variability, as well as investigate the quantitative relationship between them. Methods: Being simultaneously acquired, the pulse wave and ECG data were denoised, removed baseline drift. Then the pulse rate intervals and heart rate intervals were extracted. Finally, the relationship between the heart rate...
ECG and pulse waveforms are important physiological parameters that can be utilized to analyze noninvasively physical condition and monitor cardiovascular diseases. In recent years, they were studied for evaluating the effects of exercise on human body. However, the systematical analysis on the changes of ECG and pulse waveforms before and after exercise has not been found. This study examines the...
A method is proposed for recognizing noises in pulse waves (PWs), which play an essential role in clinical pulse diagnosis. PWs have also been used in traditional Chinese medicine for thousands of years. We follow the principle that most noises appear as pairs of adjacent sampling points. These pairs satisfy five certain criteria. The principle and the criteria are based on observation and statistical...
The variability of pulse wave was found and discussed recently. The cross-correlation of variability of the parameters of pulse wave was studied in this paper. We found that the variability of the features in time was closely related. However, the variability of the features in time had little correlation with that of the amplitude features of pulse wave. The complexity of the variability of these...
