downwards line segments in the recurrence plots because it is Single beats from ECG recording were used to demonstrate opposite in direction to the downwards part of the S wave. how the nonlinear dynamical analysis method of recurrence The effect is more prominent in figure (d) because the rise in plots can be used to qualitatively describe data. the signal is more gradual. Kevwords: nonlinear dvnamics, recurrence dot. ECG Perhaus the most notable difference between these two recurrence plots
