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