22
Q

ven/o, ven/i

A

23
Q

ventricul/o

A

ventricle, lower heart chamber

24
Q

acute coronary syndromes (ACSs)

A

unstable angina and myocardial infarcation (heart attack) which are consequences of plaque rupture in coronary arteries

25
Q

angina (pectoris)

A

chest pain resulting from myocardial ischemia. stable angina occurs predictably with exertion; unstable angina is chest pain that occurs more often and with less exertion

26
Q

angiotensin-converting enzyme (ACE) inhibitor

A

antihypertensive drug that blocks the conversion of angiotensin I to angiotensin II, causing blood vessels to dilate. it prevents heart attacks, CHF, stroke, and death

27
Q

auscultation

A

listening for sounds in blood vessels or other body structures, typically using a stethoscope

28
Q

beta-blocker

A

drug used to treat angina, hypertension, and arrhythmias. it blocks the action of epinephrine (adrenaline) at receptor sites on cells, slowing the heartbeat and reducing the workload on the heart

29
Q

biventricular pacemaker

A

device enabling ventricles to beat together (in synchrony) so that more blood is pumped out of the heart

30
Q

bruit

A

abnormal blowing or swishing sound heard during auscultation of an artery or organ

31
Q

calcium channel blocker

A

drug used to treat angina and hypertension. it dilates blood vessels by blocking the influx of calcium into muscle cells lining vessels

32
Q

cardiac arrest

A

sudden, unexpected stoppage of heart action, often leading to sudden cardiac death

33
Q

cardiac tamponade

A

pressure on the heart caused by fluid in the pericardial space

34
Q

claudication

A

pain, tension, and weakness in a leg after walking has begun, but absence of pain at rest

35
Q

digoxin

A

drug that treats arrhythmias and strengthens the heartbeat

36
Q

embolus

plural: emboli

A

clot of other substance that travels to a distant location and suddenly blocks a blood vessel

37
Q

infarction

A

area of dead tissue

38
Q

nitrates

A

drugs used in the treatment of angina, they dilate blood vessels, increasing blood flow and oxygen to myocardial tissue

39
Q

nitroglycerin

A

nitrate drug used in the treatment of angina.

40
Q

occlusion

A

closure of a blood vessel due to blockage

41
Q

palpitations

A

uncomfortable sensations in the chest related to cardiac arrhythmias, such as premature ventricular contractions (PVSc)

42
Q

patent

A

open

43
Q

pericardial friction rub

A

scraping or grating noise heard on auscultation of the heart; suggestive of pericarditis

44
Q

petechiae

A

small, pinpoint hemorrhages

45
Q

statins

A

drugs used to lower cholesterol in the bloodstream

46
Q

thrill

A

vibration felt over an area of turmoil in blood flow (as a blocked artery)

47
Q

vegetations

A

clumps of platelets, clotting proteins, microorganisms, and red blood cells on diseased heart valves
