A new method is proposed for calculating the enlargement factor in order to measure left ventricular volume. It is based on the grid method of Kasser and Kennedy, modified and simplified by making use of the technical possibilities of their apparatus. The enlargement factor is measured from a graduated scale and reference to a pre-established graph.
提出了一种计算放大因子的新方法，用于测量左心室容积。该方法基于卡塞尔和肯尼迪的网格法，并利用他们仪器的技术可能性进行了修改和简化。放大因子通过刻度标尺测量，并参考预先建立的图表。
