为初步了解高山环境对心脏电活动的影响在性别上的差异,本文对同一地区(海拔2800公尺)、同一单位男女两组正常成人心电图作比较分析。观察对象322名,都是某国营农场汉族农业工人(包括少数干部),未作任何选择。男组193名,年龄18—60岁,平均42岁,女组18—62岁,平均35岁。男组在此地区连续居留6—49年,平均15.2年,其中78.4％已11年以上;女组6—26年,平均13年,70％在11年以上。每一例都作了如本题Ⅲ文所列的各项检查,结果阴性,亦无慢性呼吸道病史,可基本肯定是健康人。女组中有少数人的心电图二级梯双倍运动试验阳性或可疑阳性,经测定血脂正常,并于静注心得安3—4毫克后重复双倍运动试验,结果阴性,方始列入本组。
To understand the gender differences in the effects of alpine environment on electrical activity of the heart, a comparative analysis of two groups of normal adult ECGs in the same area (elevation 2,800 m) and in the same unit was conducted. The 322 observation objects were all Han agricultural workers (including a few cadres) of a state-run farm and did not make any choice. 193 men, aged 18-60 years old, with an average of 42 years old, women aged 18-62, with an average of 35 years old. The male group stays in this area for 6 to 49 consecutive years, an average of 15.2 years, of which 78.4% have been over 11 years; women 6 to 26 years, an average of 13 years, 70% over 11 years. In each case, the tests as set out in Section III of this question were made. The results were negative and no history of chronic respiratory disease was found. A small number of women in the ECG double-step ladder double test positive or suspicious positive, measured by normal blood lipids, and in the intravenous injection of 3-4 mg after repeated double exercise test, the results were negative, the party was included in this group.
