[[w:Einthoven|The dutchman Willem Einthoven]] (1860-1927) introduced in 1893 the term 'electrocardiogram'. He described in '''1895''' how he used a galvanometer to visualize the electrical activity of the heart. In 1924 he received the Nobelprize for his work on the ECG. He connected electrodes to a patienta showed the electrical difference between two electrodes on the galvanometer. We still now use the term: Einthovens'leads. The string galvanometer (see Image) was the first clinical instrument on the recording of an ECG. | [[w:Einthoven|The dutchman Willem Einthoven]] (1860-1927) introduced in 1893 the term 'electrocardiogram'.
