本文介绍了一种连续分析心跳与呼吸相位关系的简单方法。借助于模拟计算机，以图形方式显示呼吸周期内心电图R波的定时。与其他研究相比，吸气的开始被用作起始信号。用模拟计算机获得的结果由数字计算机程序完成，该程序还允许计算事件的直方图。为了评估我们的方法，我们使用了两个耦合振荡器的模拟模型。在不同的耦合特性得到的反应进行了比较，在四个主题的测量。结果表明，心脏活动和呼吸之间的相互作用是这两个系统耦合的原因。
SummaryA simple method for the continuous analysis of the phase relation between heart beat and respiration is described. By means of an analog computer the timing of theR wave of the ECG within the respiratory cycle is graphically displayed. In contrast to other investigations, the onset of the inspiration is used as starting signal. The results obtained with the analog computer were completed by a digital computer program, which allowed in addition to calculate histograms of the events. In order to evaluate our method we used an analog model of two coupled oscillators. Responses obtained at different coupling characteristics were compared with measurements in four subjects. The results indicate a mutual interaction between heart action and respiration as cause of the coupling of these two systems.
