Fig. 3. — Top: averaged mean arterial pressure (MAP) increase (MAPIncrease) following a spontaneous muscle sympathetic nerve activity (MSNA) burst in smokers and nonsmokers. The averaged MAPIncrease was significantly higher in smokers than nonsmokers. Middle: product of MAPIncrease and MSNA burst rate (MSNABR) was also significantly higher in smokers than nonsmokers. Bottom: averaged heart rate (HR) decrease (HRDecrease) was significantly greater in smokers than nonsmokers. Individual data points for smokers (●, n = 18) and nonsmokers (○, n = 42) are shown on box-and-whisker plots.
