Figure 1.

The time course of heart rate and systolic blood pressure changes before and after the onset of CAP. The median value (black line) of each CAP subtype was calculated (A, B) and graphed. Gray shadows indicate interquartile range of heart rate and systolic blood pressure. Zero seconds indicates the onset of CAP. The peak time of systolic blood pressure is delayed by approximately 4 seconds compared with that of heart rate. The increase in both heart rate and systolic pressure is higher in the order of subtype A3, A2, and A1.
