Are you curious about the rhythm of your heart? If the answer is yes… On Tuesday, 12th April between 10.00 and 14.00 come to visit us at the LUMC side of the Stationsplein in Leiden. We will be celebrating the invention of the string galvanometer (the first electrocardiogram) by Willem Einthoven during his work at the University of Leiden, for which he obtained the Nobel prize in 1924. In one minute, we will make a one-lead electrocardiogram and you will discover how your heart rhythm is!
