Electrocardiography for Healthcare
Professionals – | Complete Test Bank
(Chapters 1–15) with Verified Answers
action potential - answers The change in the electrical potential of the heart muscle
when it is stimulated.
acute coronary syndrome (ACS) - answers A broad term referring to unstable angina,
ST segment elevation MI (STEMI), and non-ST segment elevation MI (NSTEMI),
usually associated with intracoronary plaque changes or thrombosis.
advanced cardiac life support (ACLS) - answers A set of clinical interventions for the
urgent treatment of cardiac arrest and other life-threatening medical emergencies.
alternating current (AC) interference - answers Unwanted markings on the ECG caused
by other electrical current sources.
ambulatory monitoring - answers The process of recording an ECG tracing for an
extended period while a patient goes about their daily activities.
anatomically contiguous lead - answers Two or more leads looking at the same part of
the heart or numerically consecutive chest leads.
angina - answers An oppressive pain or pressure in the chest due to insufficient oxygen
to the heart muscle.
angioplasty - answers A minimally invasive procedure to open narrowed or blocked
blood vessels.
angle of Louis - answers A ridge about an inch below the suprasternal notch where the
main part of the sternum and the manubrium are attached.
anomaly - answers Something that deviates from what is standard, normal, or expected.
anorexia - answers Decreased or loss of appetite.
anterior axillary line - answers An imaginary vertical line starting at the front axilla that
extends down the left side of the chest.
antidysrhythmic - answers Type of medication given to prevent cardiac rhythm
abnormalities.
, aorta - answers The largest artery of the body; transports blood from the left ventricle to
the entire body.
aortic semilunar valve - answers Valve in the aorta that prevents the backflow of blood
into the left ventricle.
apnea - answers The absence of breathing.
artifact - answers Unwanted marks on the ECG tracing caused by activity other than the
heart's electrical activity.
ascites - answers Abnormal collection of serous fluid within the abdomen, may occur
secondary to congestive heart failure.
asystole - answers A condition with no rhythm or electrical current traveling through the
cardiac conduction system.
atherosclerotic plaque - answers Fatty deposits accumulated due to elevated glucose
levels.
atrial kick - answers Blood ejected into the ventricles by the atria before ventricular
contraction, contributing to a 10%-30% increase in cardiac output.
atrial pacing - answers Electrical stimulation delivered to the atria to cause conduction
through the ventricles resulting in ventricular contraction.
atriobiventricular pacing - answers Sequential pacemaker stimulation of the atria and
then both ventricles, also known as biventricular pacing.
atrioventricular (AV) node - answers Delays the electrical impulse to allow the atria to
complete their contraction.
atrioventricular sequential pacing - answers A pacemaker stimulation of the atria and
then the lower part of the right ventricle in a sequence that mimics the normal cardiac
conduction system.
atrium (pl. atria) - answers Top two chambers of the heart.
augmented leads - answers Small ECG lead tracings increased in size by the ECG
machine for interpretation.
auscultated blood pressure - answers Blood pressure determined while listening with a
stethoscope.
automatic external defibrillator (AED) - answers A portable device that recognizes
abnormal rhythm and determines if it is a 'shockable rhythm.'
