electrocardiograph

(ĭ-lĕk′trō-kär′dē-ə-grăf′)
n.
An instrument used in the detection and diagnosis of heart abnormalities that measures electrical potentials on the body surface and generates a record of the electrical currents associated with heart muscle activity. Also called cardiograph.

electrocardiograph (ECG)

[-kär′dē·əgraf′]
a device used for recording the electrical activity of the myocardium to detect transmission of the cardiac impulse through the conductive tissues of the muscle. Electrocardiography allows diagnosis of specific cardiac abnormalities. Leads are affixed to certain anatomical points on the patient's chest, usually with an adhesive gel that promotes transmission of the electric impulse to the recording device. electrocardiographic, adj.

(ĕ-lek'trō-kahr'dē-ō-graf)
An instrument for recording the potential of the electrical currents that traverse the heart.

electrocardiograph

An instrument consisting of a series of electrical cables (leads) with a lead-switching device, a high-gain, low-noise, balanced differential amplifier and a moving coil rotary transducer that converts the amplified signal into a varying trace on a calibrated strip of moving paper. The leads are connected to low-resistance contacts on the chest of the subject and the input to the device is derived from the minute electrical currents that flow towards and away from them as a result of the heart's contractions and relaxations.

Electrocardiograph (ECG, EKG)

A test of a patient's heartbeat that involves placing leads, or detectors, on the patient's chest to record electrical impulses in the heart. This test will produce a strip, or picture record of the heart's electrical functioning.
