摘要
目的观察高原野战增压帐篷（增压帐篷）对急进高原健康人心脏的影响。方法由低海拔平原（北京，31．2m）急进高原（拉萨，3680m）的健康人30人随机均分为2组，分别监测在增压帐篷和普通帐篷内早8时～18时的动态心电图，并描记常规12导联心电图，分析2组受试者心律失常发生率和有关心电图指标。结果增压帐篷组窦性心律失常和早搏发生率分别为40．00％和33．33％，均显著低于普通帐篷组（分别为66．67％和53．33％，均P〈0．05）。与普通帐篷组比较，增压帐篷组心室率为80．860次／min，显著低于普通帐篷组（89．02次／min），增压帐篷组QRS时限和Q—Tc分别为（0．088±0．017）s和（0．428±0．0310）s，均显著短于普通帐篷组[分别为（0．072±0．013）s和（0．391±0．029）s，均P〈0．05]。增压帐篷组P—R间期和Q—T间期为（0．149±0．062）s和（0．350±0．028）s，与普通帐篷组[（0．162±0．068）s和（0．335±0．031）s]无显著差异（均P〉0．05）。结论高原野战增压帐篷能有效纠正急性高原低压性缺氧，对心脏有保护作用。
Objective To observe the effects of highland field pressure- increasing tabernacle on the cardiac function of healthy persons who urgently enter the highland. Methods Thirty healthy males, aged （37.60±3.12） （27 ± 52）, without history of highland residence who were sent from Beijing, with an elevation of 31.2 m rapidly to Lhasa, with an altitude of 3680 m, were randomly divided into 2 equal groups： Group A residing in highland field pressure-increasing tabernacles and Group B residing in an ordinary tabernacle. Dynamic electrocardiography was conducted from 8am to 6pro, and by the end of the test routine 12-lead electrocardiogram was recorded. The rate of arrhythmia and the parameters of electrocardiogram were analyzed. Results The rates of sinus arrhythmia and early premature systole of Group A were 40.00% and 33.33% respectively, both significantly lower than those of Group B （66.67% and 53.33% respectively, both P〈 0.05）. The heart rate of Group A was 80.86 bpm, significantly lower than that of Group B （89.02 bpm, P〈0.05）. The QRS complexes duration and Q-Tc interval of Group A were （0.072±0.013） s and （0.391±0.029） s respectively, both significantly shorter than those of Group B [（0.088±0.017） s and （0.428±0.031） s respectively, both P〈0.05] . The P-R and Q-T intervals of Group A were （0.149±0.062） s and （0.350±0.028） s respectively, both not significantly different from those of Group B [（0.162±0.068） s and （0.335±0.031） s respectively both, P〉 0.05）. Conclusion Highland field pressure-increasing tabernacle effectively prevents acute highland hypobaric hypoxia and keeps normal heart functionality.
