【摘要】：[目的]观察急进高原对武警战士心脏和血管功能影响,为探讨新兵高原习服提供科学依据。[方法]实验于2008年在成都和拉萨完成。用XXG-E3型自动心血管功能诊断仪记录平原、急进高原d 1、d 3、d 5、d 7心脏和血管功能指标。[结果]①与平原比较,急进高原的d 1、d 3,脉搏速率加快(P㩳0.001),d 3、d 5、d 7搏出量和心搏指数减少(P㩳0.01),d 5、d 7心脏指数减少(P㩳0.05,P㩳0.001),d 7心输出量减少(P㩳0.001),d 5、d 7有效循环血量减少(P㩳0.001),d 3、d 7心肌血流灌注量减少(P㩳0.001),心肌耗氧指数、心肌耗氧量、心搏功指数、心肌血流需要量的差别均无统计学意义。②与平原比较,急进高原d 5、d 7,脉搏压减小,d 3、d 7血管顺应度、血管弹性系数、主动脉排空系数减小(P㩳0.001,P㩳0.05),d 3、d 5、d 7总外周阻力、标准周阻增大(P㩳0.001,P㩳0.05),肺动脉阻力、肺动脉压的变化差异无统计学意义。[结论]急进高原心脏功能的变化主要为心率加速和搏出量减少;对血管的影响主要是增加体循环外周阻力。
[Abstract]:[objective] to observe the effect of rapid entry on the heart and vascular function of armed police soldiers, and to provide scientific basis for investigating the acclimatization of recruits at high altitude. [methods] the experiment was carried out in Chengdu and Lhasa in 2008. The cardiac and vascular function indexes were recorded by XXG-E3 automatic cardiovascular function diagnostic instrument on the plain and into the plateau on the first day, 3 days, 5 days, 7 days. [results] 1Compared with plain, The pulse rate increased with the increase of pulse rate (P < 0.001 / d = 5 / 7), and the decrease of cardiac output and cardiac index decreased by 0.01g / d / 7 / d / 7 / d / 7 / day / day high / high altitude respectively. There was no significant difference in myocardial oxygen consumption, cardiac stroke work index and myocardial blood flow requirement between the two groups. The aortic emptying coefficient decreased with the increase of the standard circumference (P0. 001), the change of pulmonary artery resistance and pulmonary artery pressure was not statistically significant (P < 0. 001). The total peripheral resistance was reduced by 0. 001 ~ 0. 05 / d / d 3 / d / 5 / d ~ (7), and the standard circumference was increased (P = 0. 001 / P ~ 0. 05). [conclusion] the main changes of cardiac function at high altitude are the acceleration of heart rate and the decrease of cardiac output, and the effect on blood vessels is mainly to increase the peripheral resistance of systemic circulation.
