cardiovascular Flashcards
structural defects involving heart valves are likely to create an audible turbulence known as an
murmur
_ pressure is peak pulse pressure created when the ventricles are contracting
systolic
Abnormal heart sounds created by blood turbulence are called murmurs. Some murmurs may be caused by abnormally narrow vessels or valves. This condition of narrowing is medically termed ___.
stenosis
A veterinary professional who specializes in the study of the heart and heart disease is called ___.
Cardiologist
Which anatomical area is most likely to demonstrate visible change when an animal is experiencing low oxygenation?
Mucous membranes
The__ is pacemaker of the cardiac conduction system
sinoatrial node
Inadequate blood volume or low hemoglobin concentration result in what color mucous membranes
white
The valve located between the left ventricle and the left atrium is the ___.
left atrioventricular valve
Inflammation of the interior lining of the heart is called ___.
endocarditis
A(n) ___ is any condition in which the heart has an abnormal rhythm. Ventricular premature complexes are the most common type seen
Arrhythmia
A condition in which the heart is beating more rapidly than normal is medically termed ___.
Tachycardia
The medical term for heart muscle is
myocardium
A(n) __ is the smallest type of blood vessel in the body through which gas exchange (oxygen and carbon dioxide) takes place
Capillary
A(n) ___ agent is any drug used to suppress coughing
Antitussive
Dirofilaria immitis is the scientific name of the __.
canine heartworm
Which vein is used to collect a large amount of blood in a short time?
Jugular
The absence of any cardiac contraction is medically termed
Asystole
__is the phase of the cardiac cycle when heart muscle is contracting
Systole
What vessel carries oxygenated blood toward the heart?
pulmonary vein
The __ septum separates the left ventricle from the right ventricle
Interventricular
The __ is the specific electrical impulse recorded on the electrocardiographic tracing that is directly associated with firing of the sinoatrial node and atrial depolarization
P wave
The pulmonic and aortic valves are closed during the __ phase of the cardiac cycle
diastolic
Dilatory__ is a disease of heart muscle that is most commonly seen in dogs. The Large ventricular chamber size in these animals often contributes to a distinct third heart sound.
Cardiomyopathy
Positive __ agents, such as epinephrine, have a profound influence on the strength of myocardial contraction
inotropic
