The systolic time intervals (STI) are reliable parameters for the characterization of left ventricular heart function. The non-invasive methods for the determination of STI are here introduced and compared. The disadvantage of all these methods is their manual evaluation of time intervals which makes a continuous monitoring of STI impossible. Therefore, a microprocessor based system was developed for the automatic registration of STI, stroke time volume (SV) and heart rate from the impedance cardiogram (ICG) and the electrocardiogram (ECG). In this article the preliminary results are discussed of the long-term monitoring of these parameters with the help of this device.
收缩期时间间期（STI）是用于表征左心室心功能的可靠参数。本文介绍并比较了测定STI的非侵入性方法。所有这些方法的缺点是对时间间期进行人工评估，这使得对STI进行连续监测成为不可能。因此，开发了一种基于微处理器的系统，用于从阻抗心动图（ICG）和心电图（ECG）自动记录STI、每搏输出量（SV）和心率。本文讨论了借助该设备对这些参数进行长期监测的初步结果。
