The heart rate during whole day, periods of activity and sleep as well as repeatable daily activities were identified in a group of 22 women, aged 19-40, and pregnant for 12-36 weeks, following a 24-hour recording of the heart work. In four women only, mean circadian heart rate was under 87/min, a value considered as normal in moderate active persons. That indicates a significant pregnancy-related increase of heart rate. A considerable great variation of heart rates was observed during a day. The highest heart rate (97-140/min) was caused by mounting the stairs; it was also noted during performing minor household jobs and/or preparing meals. While using transportation means, heart rate ranged from 78 to 130/min, and at leisure form 89 to 108/min. It was found that the level of an acceptable load for women (100 heart beats/min) was already higher than the mean value for the whole period of activity. An analysis of the relationship between heart rate in certain situations and the age of women under study, and the pregnancy advancement, shows that heart rate was, in each period of recording, positively correlated with the women's age. That means an increasing, with age pregnancy-related load. Heart rate during a 24-hour period, periods of activity and sleep, during the use of transportation means, watching television and resting in a sitting position, was positively correlated with the duration of pregnancy. Negative correlation between heart rate and the duration of pregnancy was observed while mounting the stairs, preparing meals and performing other household jobs. The negative correlation indicates that the pace of activities performed can be easily regulated, and thus, the load magnitude adjusted to physical abilities, whereas the positive correlation indicates that such a possibility does not exist in regard to the expenditure of energy (work pace). To sum up, the data presented shows that the use of transportation means increased the women's load but they could easily perform minor household jobs. However, there were no occupationally working women in the study group, it can be concluded that this kind od analysis, and conclusions drawn, can be used in identifying types of work and workplaces which pose too much load to pregnant women.
在对22名年龄在19至40岁、怀孕12至36周的女性进行24小时心脏活动记录后，确定了她们全天、活动期间、睡眠期间以及日常重复性活动的心率。仅在4名女性中，平均昼夜心率低于87次/分钟，这一数值在中等活动量的人群中被视为正常。这表明怀孕与心率显著增加有关。一天中观察到心率有相当大的变化。爬楼梯时心率最高（97 - 140次/分钟）；在做一些轻微家务和/或准备饭菜时也会出现这种情况。乘坐交通工具时，心率范围为78至130次/分钟，休闲时为89至108次/分钟。研究发现，女性可接受的负荷水平（100次心跳/分钟）已经高于整个活动期间的平均值。对特定情况下的心率与所研究女性的年龄以及怀孕进展之间关系的分析表明，在每个记录时间段，心率与女性年龄呈正相关。这意味着随着年龄增长，与怀孕相关的负荷增加。24小时期间、活动和睡眠期间、乘坐交通工具期间、看电视以及坐着休息时的心率与怀孕时长呈正相关。在爬楼梯、准备饭菜和做其他家务时，观察到心率与怀孕时长呈负相关。这种负相关表明所进行活动的节奏可以很容易地调节，从而将负荷大小调整到身体能力范围内，而正相关则表明在能量消耗（工作节奏）方面不存在这样的可能性。总之，所呈现的数据表明乘坐交通工具增加了女性的负荷，但她们能够轻松完成轻微家务。然而，研究组中没有职业女性，由此可以得出结论，这种分析及所得出的结论可用于识别对孕妇负荷过大的工作类型和工作场所。
