Anatomy and Physiology EKG Exam
Questions and Answers Graded A+
1. Acute coronary syndrome (ACS): - Correct answer-A term used to refer to
distinct conditions caused by a similar sequence of pathologic events- a temporary
or permanent blockage of a coronary artery; these conditions are characterized by
an excessive demand or inadequate supply of oxygen and nutrients to the heart
muscle associated with plaque disruption, thrombus formation, and
vasoconstriction, ACSs consists of three major syndromes: unstable angina (UA),
non -ST- segment elevation myocardial infarction (NSTEMI), and ST- segment
elevation myocardial infarction (STEMI).
2. Adrenergic: - Correct answer-Having the characteristics of the sympathetic
division of the autonomic nervous system.
3. Afterload: - Correct answer-The pressure or resistance against which the
ventricles must pump to eject blood.
4. Angina pectoris: - Correct answer-Chest discomfort or other related symptoms
of sudden onset that may occur because the increased oxygen demand of the heart
temporarily exceeds the blood supply.
, 5. Aortic valve: - Correct answer-SL valve on the left of the heart; separates the left
ventricle from the aorta.
6. Apex of the heart: - Correct answer-Lower portion of the heart that is formed by
the tip of the left ventricle.
7. Arteriosclerosis: - Correct answer-A chronic disease of the arterial system
characterized by abnormal thickening and hardening of the vessel walls.
8. Atherosclerosis: - Correct answer-A form of arteriosclerosis in which the
thickening and hardening of the vessel walls are caused by a buildup of fatty
deposits in the inner lining of large and middle- sized muscular arteries (from
athero, meaning gruel or paste, and sclerosis, meaning hardness).
9. Atria: - Correct answer-Two upper chambers of the heart (singular, atrium).
10. Atrial kick: - Correct answer-Blood pushed into the ventricles because of atrial
contraction
11. Atrioventricular valve: - Correct answer-valve located between each atrium and
ventricle; the tricuspid separates the right atrium from the right ventricle, and the
mitral (bicuspid) separates the left atrium from the left ventricle.
12. Atypical presentation: - Correct answer-Uncharacteristic signs and symptoms
perceived by some patients experiencing a medical condition, such as an ACS.
