electrocardiograph

 [e-lek″tro-kahr´de-o-graf″]
the apparatus used in electrocardiography.

e·lec·tro·car·di·o·graph

(ē-lek'trō-kar'dē-ō-graf), Do not confuse this word with electrocardiogram.
An instrument for recording the potential of the electrical currents that traverse the heart.

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.

(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.
