． 本文研究了15例高血压患者持续握力对血流动力学的影响。其反应模式与血压正常者相似，表现为收缩压、舒张压和平均动脉压明显升高，心率和心输出量中度升高，中心静脉压、搏量和总外周阻力无变化。在静态肌肉收缩时，我们发现患者的平均动脉血压高于正常者，而在动态运动时，高血压患者的动脉血压高于正常者。
. The haemodynamic responses to sustained handgrip were studied in 15 hypertensive patients. The response pattern was found to be similar to that in normotensive subjects, and was characterized by marked increase in systolic, diastolic and mean arterial pressure, moderate increase in heart rate and cardiac output, and no change in central venous pressure, stroke volume or total peripheral resistance. Mean arterial blood pressure was found to be higher in our patients than it is in normotensive subjects during static muscular contraction, and higher than it is in hypertensive subjects during dynamic exercise.
