Questions and Correct Answers/ Latest
Update / Already Graded
amplifier
Ans: a device on an electrocardiograph that enlarges the ECG
impulses.
artifacts
Ans: something extraneous to what is being looked for; activity
that causes interference on ECGs.
atrial depolarization
Ans: the excitement and contraction caused by the SA node at
the beginning of the cardiac cycle.
augmented
Ans: refers to leads 4, 5, and 6 of the standard 12-lead ECG
tracing; these leads are of different voltage.
cardiology

, Page |2
Ans: the study of the heart and its diseases.
countershock
Ans: (in cardiology) a high-intensity, short-duration, electric
shock applied to the area of the heart, resulting in total cardiac
depolarization.
current
Ans: the heart's electrical activity as waveforms moving
through the heart.
defibrillator
Ans: a device designed to deliver an electric shock to a pa tient,
in an effort to stop pulseless ventricular fibrillation or
ventricular tachycardia.
echocardiography
Ans: ultrahigh-frequency sound waves directed toward the
heart to evaluate function and structure of the organ.
echoes

Ans: reflections of sound.
electrocardiogram
Ans: a graphic record of the electric currents generated by the
heart; a tracing of the heart action; may also be referred to as
an ECG or EKG.
electrodes
Ans: an instrument with a point or a surface that transmits
current to the patient's body; also known as a sensor used to
conduct electricity from the body to the electrocardiograph.
galvanometer
Ans: an instrument that measures current by electromagnetic
action.
Holter monitor
Ans: a device that attaches electrodes to a patient's chest for
the purpose of obtaining a 24-hour ECG tracing in an accessory
tape recorder.
