Etymology: "Myocardiographs" is the plural of "myocardiograph," a noun for an instrument that records the rhythm of the heart. The word is built from three parts: "myo-," from Greek "mys," meaning muscle; "cardio-," from Greek "kardia," meaning heart; and "-graph," from Greek "graphein," meaning to write or record. Put together, the parts describe a device that writes down the activity of the heart muscle. The pattern is typical of modern scientific coinage. The Greek building blocks were ancient, but the compound itself was assembled from them much later, when physicians and engineers needed precise names for new instruments. Each element carries its meaning transparently, so a reader can work out the sense from the parts alone. Because "myocardiograph" is a plain compound of classical roots, its history is simple: the word names a recording device, and its plural simply follows the usual English rule of adding "-s."

Synonyms: heart monitors, cardiac monitors, ECGs, electrocardiographs, heart recorders
