Personal microcomputers interfaced with analog-digital converters are capable of analyzing almost any biological signal, yet are limited in their ability to directly measure a signal's period/frequency. We describe a short program which measures the interval between periodic events up to 3.5 Hz. In addition, an expanded program which calculates the frequency distribution, distribution statistics, and cross regressions of cardiac interval and blood pressure is described.
与模拟数字转换器相连的个人微型计算机能够分析几乎任何生物信号，但在直接测量信号的周期/频率方面能力有限。我们描述了一个短程序，它可以测量高达3.5赫兹的周期性事件之间的间隔。此外，还描述了一个扩展程序，它可以计算心搏间期和血压的频率分布、分布统计以及交叉回归。
