Cardiogoniometry is a new method to test heart function. It consists of a simple computerized vectorcardiography with a system of leads derived for the construction of three orthogonal projections. With the aid of these three-dimensional projections the cardiogoniometer, a microprocessor system, measures and computes the maximal vectors of depolarization (QRS) and repolarization (T). It also fixes the orientation of these two spatial vectors by projection on two planes (frontal and oblique sagittal) and determines the solid angle phi between them. Every third heart beat these five parameters and the preceding beat interval are printed out. In this way, a series of measurements is obtained in which only little disturbances of the signals of cardiac de- and repolarization occur. In patients with latent coronary insufficiency an abnormal position of the T vector can be detected long before the standard ECG shows a pathological pattern. Cardiogoniometry can be performed in the consulting room or at the bedside. It is noninvasive, painless, and free of risk. The value and limits of this new method are to be tested in comparison with the ECG and invasive methods in cardiology laboratories.
心角测量法是一种测试心脏功能的新方法。它由一种简单的计算机化向量心电图组成,带有一个用于构建三个正交投影的导联系统。借助这些三维投影,心角测量仪(一种微处理器系统)测量并计算去极化(QRS)和复极化(T)的最大向量。它还通过投影在两个平面(额面和斜矢状面)上确定这两个空间向量的方向,并确定它们之间的立体角φ。每隔三个心跳,这五个参数以及前一个心跳间期就会被打印出来。通过这种方式,可以获得一系列测量结果,其中心脏去极化和复极化信号的干扰很小。在潜在冠状动脉供血不足的患者中,早在标准心电图显示病理模式之前就能检测到T向量的异常位置。心角测量法可以在诊室或床边进行。它是非侵入性的、无痛的且无风险。这种新方法的价值和局限性有待与心电图和心脏病学实验室中的侵入性方法进行比较测试。
