A twenty-four-hour blood pressure (BP) monitoring was performed in 20 normotensive and 20 hypertensive subjects, matched by sex and age. Blood pressure and heart rate (HR) variability were evaluated both as absolute and percent standard deviation. In agreement with the literature no significant difference in HR and BP variability was observed between the two groups. The linear regression between HR and BP values was evaluated in both groups. The authors observed a significant difference in the relationship between these two cardiovascular variables between the two groups. In the hypertensive group the cardiovascular control of HR and BP showed a different relationship than in normotensive subjects, suggesting a different neurovegetative modulation.
对20名血压正常和20名高血压受试者进行了24小时血压（BP）监测，两组受试者在性别和年龄上相匹配。血压和心率（HR）变异性均以绝对标准差和标准差百分比进行评估。与文献一致，两组之间在心率和血压变异性方面未观察到显著差异。对两组的心率和血压值之间的线性回归进行了评估。作者观察到两组之间这两个心血管变量之间的关系存在显著差异。在高血压组中，心率和血压的心血管控制显示出与血压正常受试者不同的关系，提示存在不同的神经调节。
