It is shown that appraisal and comparison of the duration of the R-R intervals in continuous surveillance of patients by means of electronic computers on the on-line regimen provides for automatic diagnosis of most types of disorders of the cardiac rhythm. The elaborated criterion of arrhythmic cardiac contraction (ACR-R), which takes into account not only the absolute value of the time between heart contractions but also the trend of the changes in the next R-R interval, provides a high percentage of revealed arrhythmic contractions. Disorders of the rate of cardiac contractions may be diagnosed by means of an electronic computer by comparison between the mean value of intervals of normal duration and the preset threshold values. Disorders of the rhythm may be diagnosed by means of an electronic computer by assessment and comparison of the arrangement of the combinations of short, normal, and long R-R intervals. The elaborated algorithms are described in detail and the block diagrams of the programs are shown.
结果表明，通过在线方式利用电子计算机对患者进行连续监测时，对R-R间期持续时间进行评估和比较，可自动诊断出大多数类型的心律失常。所制定的心律失常性心脏收缩标准（ACR-R）不仅考虑了心脏收缩之间时间的绝对值，还考虑了下一个R-R间期的变化趋势，从而使检测到的心律失常性收缩的比例很高。心脏收缩速率的紊乱可通过电子计算机将正常持续时间间期的平均值与预设阈值进行比较来诊断。心律失常可通过电子计算机对短、正常和长R-R间期组合的排列进行评估和比较来诊断。详细描述了所制定的算法，并展示了程序的框图。
