Opis:

In contrast to what the name of this file may suggest, this picture does not represent the ECG machine built by Willem Einthoven and his team. It shows an early commercial ECG machine, built in 1911 by the Cambridge Scientific Instrument Company (Christoph Zywietz, A Brief History of Electrocardiography - Progress through Technology; S. L. Barron, The development of the electrocardiograph in Great Britain, British Medical Journal 1:720, 25 March 1950) to measure the human electrocardiogram according to the standards developed by Einthoven.
