Which of the following is associated with the electrocardiograph?

The electrocardiograph records the heart’s electrical activity, and its invention is credited to Willem Einthoven, who built the first practical device and produced the first recognizable electrocardiograms. He developed the string galvanometer that could detect the tiny electrical signals from the heart, and he introduced the standard limb-lead configuration known as Einthoven’s triangle, which underpins how ECGs are interpreted today. His work earned him the Nobel Prize in Physiology or Medicine in 1924. The other names listed are notable in different fields—Helmholtz in physics and physiology, Garcia in voice studies, and Pasteur in microbiology—so they are not associated with the invention of the electrocardiograph.
