We conclude that in clinically unchanged conditions, the time-domain HR variability measures derived from 24-hour ambulatory recordings of AMI survivors are stable during the early convalescent phase, and the day-to-day differences have only little effect on the result. The only exception appears to be the pNN50 parameter, the use of which should be favorably substituted by the rMSSD measurement. Geometric estimates of HR variability are highly and consistently correlated with statistical measures of overall HR variability, and may be used as substitutes for each other.
我们得出结论,在临床状况未改变的情况下,急性心肌梗死幸存者24小时动态记录得出的时域心率变异性测量值在康复早期阶段是稳定的,且每日差异对结果影响甚微。唯一的例外似乎是pNN50参数,其应用最好由rMSSD测量值替代。心率变异性的几何估计值与整体心率变异性的统计测量值高度且一致相关,可相互替代使用。
