Etymology:
Meaning:
A cardiogram is a graphic recording of the electrical activity of the heart.
Origin:
The term "cardiogram" was first used in 1887 by the Dutch physiologist Willem Einthoven, who invented the electrocardiograph (ECG), a device used to measure and record the heart's electrical impulses.
The ECG measures the electrical signals generated by the heart's muscle cells as they contract. These signals are recorded on a graph paper, creating a cardiogram that shows the heart's electrical activity over time.
Cardiograms are used to diagnose and monitor a wide range of heart conditions, including arrhythmias (irregular heart rhythms), myocardial infarction (heart attack), and heart failure.
