Abstract

OBJECTIVES

Normal activity monitoring methods are mainly useful for relatively healthy and ablebodied people, but are not necessarily appropriate for elderly persons who may have difficulty in walking, or for the frail who may be bedridden. The purpose of this study was to examine 24-hour heart rate recording for the comparison of activity levels in daily life of elderly persons of different ambulatory abilities.

METHODS

Forty-two elderly females (mean, 82.1 years old) volunteered to participate in this study. The subjects were divided into four groups on the basis of their ambulatory status, and their 24-hour heart rate recordings were compared with their results of activity assessments.

RESULTS

The results of activity assessments showed a tendency to decrease as the ambulatory ability of the group decreased. The "total heart beats", calculated as the sum of all heart rates over 24 hours, were almost the same among the four groups, and therefore did not show a similar tendency. However, the "total excess-beats product (TEBP)" correlated with the results of activity assessments. TEBP was calculated as the sum of all differences in beats between each heart rate in 24 hours and the mean heart rate during sleeping at night. Therefore, TEBP may reflect a more active state than the bedridden state.

CONCLUSIONS

These results suggest that comparison of activity levels in daily life using 24-hour heart rate recording might be possible by the calculation of TEBP, and that this method might be useful for the comparison of the activity levels of elderly persons of diffent ambulatory abilities.

摘要

目的

常规活动监测方法主要适用于相对健康、身体健全的人群，但对于可能存在行走困难的老年人或可能卧床不起的体弱人群，这些方法可能并不适用。本研究旨在通过 24 小时心率记录来比较不同活动能力老年人的日常生活活动水平。

方法

42 名老年女性（平均年龄 82.1 岁）自愿参加了这项研究。根据其活动能力，将受试者分为四组，并将他们的 24 小时心率记录与他们的活动评估结果进行比较。

结果

活动评估结果显示，随着组活动能力的降低而呈下降趋势。“总心跳数”是 24 小时内所有心率的总和，在四组之间几乎相同，因此没有表现出类似的趋势。然而，“总额外心跳乘积（TEBP）”与活动评估结果相关。TEBP 是通过计算 24 小时内每一次心率与夜间平均睡眠心率之间的差值总和得出的。因此，TEBP 可能反映出比卧床状态更活跃的状态。
