|
How does heart failure work?
|
Reduces cardiac output, increased HR, BV constriction, water retention, expanding circulating blood, increase tissue perfusion
|
|
What side of the heart thickens with Hypertension?
|
Left ventricle (heart works harder to pump out blood)
|
|
What happens if hypotension is occurring?
|
Low oxygen to the body
|
|
What do Positive Inotropic drugs do?
|
Increases the force of the myocardial contraction
|
|
What do Negative Inotropic drugs do?
|
Decreases the force of myocardial contractions
|
|
What do Positive Chronotropic drugs do?
|
Increase heart rate by altering the rate of impulse from the SA node
|
|
What do Negative Chronotropic drugs do?
|
Decrease heart rate by altering the rate of impulse from the SA node
|
|
What do Positive dromotropic drugs do?
|
Increase the conduction of electrical impulses
|
|
What do Negative dromotropic drugs do?
|
Decrease the conduction of electrical impulses
|
|
Example of positive Inotropic cardiac glycoside drugs
|
Digoxin/Digitoxin
|
|
What does Digoxin do?
|
Increase contraction, decrease HR, decrease dyspnea
|
|
Side effects of Digoxin?
|
Arrhythmias
|
|
Examples of positive inotropic catecholamines?
|
Epinephrine, Dopamine, Dobutmaine
|
|
What does epinephrine (A B) do?
|
Bronchodilation, increase BG, increase HR and contractility
|
|
Side effects of epinephrine?
|
Arrhythmias and hypertension
