title: Semiautomatic-planimetric analysis of the BCG (by means of an electrointegrationset).
abstract: The present invention is based on the use of two ballistic galvanometers in connection with an ECG-Bcg set, making it unnecessary to change poles mechanically each time in order to take in surface values above and below the zero line. A further advantage is that surface portions above and below can be dealt with simultaneously, i.e. with the same surface and without having to wait for the subsequent one(s), which already could have changed. The indicated values of the ballistic galvanometer can, on the one hand, be read directLy or, on the other hand, be documented mechanically by means of a film camera or by a photographic camera with or without different adjustable time delays or by electronic coupling after applying the measurement(s).
