Home > Specialties > Electrocardiographs


Definition : Cardiographs designed for recording the variations of the electric potential caused by the electrical activity of the heart muscle, usually detected at the body surface. Leads affixed to certain anatomic points of the patient transmit the electrical signals to the recorder, which in turn reproduces their characteristics in an amplitude versus time graph (electrocardiogram). Electrocardiographs are used to study the action of the heart muscle, for diagnosis of specific cardiac abnormalities, and to reveal trends or changes in heart function.
