Investigating Properties of the Cardiovascular System Using Innovative Analysis Algorithms Based on Ensemble Empirical Mode Decomposition

Figure 6

Illustration of phase shift between cardiac oscillations extracted from ECG and blood pressure. Plots from top to bottom are ECG signal, IMF 6 derived from ECG, time-phase distribution of ECG cardiac oscillation, BP, IMF 6 derived from BP, time-phase distribution of BP cardiac oscillation. Phase shift can be observed as the difference between the accumulative time-phase distributions of cardiac oscillations for ECG and BP.
