The Effects of Hemodynamic Changes on Pulse Wave Velocity in Cardiothoracic Surgical Patients

Figure 3

The relationship between PWV and HR, SV, CO, and SVR. Each line indicates a simple linear regression line within subject. (a) The relationship between PWV and HR. (b) The relationship between PWV and SV. (c) The relationship between PWV and CO. (d) The relationship between PWV and SVR. The median (IQR) slope and the median (IQR) P value are presented in each graph. CO: cardiac output, HR: heart rate, IQR: interquartile range, PWV: pulse wave velocity, SV: stroke volume, and SVR: systemic vascular resistance.
