'''1939''' Langendorf reports a case of atrial infarction discovered at autopsy which, in retrospect, could have been diagnosed by changes on the ECG. Langendorf R. Elektrokardiogramm bei Vorhof-Infarkt. Acta Med Scand. 1939;100:136.

'''1942''' Emanuel Goldberger increases the voltage of Wilson's unipolar leads by 50% and creates the augmented limb leads aVR, aVL and aVF. When added to Einthoven's three limb leads and the six chest leads we arrive at the 12-lead electrocardiogram that is used today.
