The resting state of the heart is also called the _______ period | |
sympathetic nerve endings release ______ and _____ near the SA node | |
Ventricular ______ degenerates to ventricular fibrillation | |
These work in 1 of 3 ways, by relaxing smooth muscle in walls, blocking alpha 1 receptors, or blocking the renin-angiotensin system | |
Repolarization is the flow of ions ____ cardiac cells | |
topical hemostatic used after dehorning | |
term for something that can lyse a blood clot | |
decrease the rate of sodium entry into damaged heart muscle cells, used to treat ventricular arrythmias in emergencies, during anesthesia, and long term (PVC's, v tach, v fib) | |
A group of damaged muscle cells, allowing sodium leakage into the cell more rapidly than normal, is called an _____ ____ | |
Which receptor type is associated with the sympathetic nervous system? | |
During depolarization, _______ slowly flows in | |
T or F, beta blockers should be stopped by slowly weaning off | |
The nerve associated with the parasympathetic system is the _____ nerve | |
Stimulation of adrenergic receptors _____ the heart | |
synthetic drug class that blocks acetylcholine and is used during sedation and anesthesia | |
These block the Na-K pump, resulting in more Ca staying in cell for contraction, increasing the strength of contraction | |
decreased heart rate | |
these drugs aid in clotting | |
| Question | answer |
Parasympathetic nerve endings release ______ near the SA node | |
These prevent conversion of angiotensin I to angiotensin II, prevent production of aldosterone, and prevent vasoconstriction and reduce water retention | |
increased heart rate | |
What adrenergic receptors are located in the smooth muscle of the bronchioles, coronary blood vessels, and skeletal muscle blood vessels? | |
A series of rapid irregular contractions of the ventricles | |
Which receptor type is associated with the parasympathetic nervous system? | |
blood clots are called _____ | |
The SA node is located in the ____ _____ of the heart. | |
drugs that increase heart rate at the SA node | |
During repolarization, _______ flows out | |
A series of rapid irregular contractions of the atria | |
more beta 1 receptors are produced to compensate for the blocking action of beta blockers, this is known as _______ | |
These block the flow of calcium into the cardiac muscle cell, slowing contraction; used in atrial tach, fibrillation, and flutter | |
body's natural chemicals released by the sympathetic nervous system, only used in emergencies for cardiac resuscitation and anaphylactic reactions | |
drugs that decrease heart rate at the SA node | |
Sodium enters _____ cells faster than normal, so these may drive the beat of the heart | |
A single abnormal ventricular contraction | |
Cardiac Disease can result in ____ _____ | |
This is readily absorbed through skin and MM, is given as a topical cream and patch applied to hairless areas, and should be handled with gloves as it can lower your BP if absorbed | |
ventricular fibrillation degenerates to ______ | |
The normal heart rhythm is driven by the ______. | |
Atrial and ventricular _______ are rapidly fatal if not treated | |
topical hemostatic used after surgical procedures | |
Parenteral hemostatic drug used to treat bleeding disorders and rodenticide poisoning | |
Stimulation of Beta 2 receptors causessmooth muscle ______ resulting in broncho_________ and vaso________of blood vessels to heart and muscles | |
| Question | answer |
Vasodilator drugs only work using a single mechanism, the other mechanisms eventually compensate for the drug and hypertension reoccurrs, this is known as vasodilator _______, | |
Activation of the atria shows on what on an ECG? | |
Stimulation of cholinergic receptors _____ the heart rate | |
The P wave and QRS complex are when the heart is a) depolarizing or b) repolarizing? | |
Depolarization is the flow of ions ____ cardiac cells | |
This hemostatic drug is used to treat heparin overdose | |
This anticoagulant is used to lyse thrombi within blood vessels, it 'chews up' clots | |
During depolarization, _______ rapidly flows in | |
Name the two types of receptors in the heart. | |
decreased platelet numbers is called __________ | |
Stimulation of Alpha 1 receptors causes contraction of smooth muscle in ______ blood vessels causing increased/decreased blood in areas that don't need it | |
_______ agents increase the production of RBCs | |
sodium influx inhibitor drug of choice to treat VPCs and v tach in an emergency, use IV only, cats are more sensitive to toxicity | |
Activation of the ventricles is shown by what on an ECG? | |
The T wave is when the heart is a) depolarizing or b) repolarizing? | |
drugs that increase the force of heart contraction are called _____ _______ | |
topical hemostatic used to stop bleeding toenails | |
During depolarization, _______ channel is closed | |
Name one drug used to prevent blood clots | |
What beta receptors do we want to block with beta blockers? | |
drugs that decrease the force of heart contractions are called _____ ______ | |
long term control of bradycardia is accomplished by use of a ________ | |
name an erythropoietic agent | |
During repolarization, _______ channel is closed | |
|
