norepi high dose impacts

A

a

33
Q

class I

A

blocks Na channels

34
Q

how do class 1 drugs work

A

prolongs the absolute refractory period and decreases the risk of premature impulses, decreses automaticity

35
Q

examples of class 1 drugs

A

quindine
procaniamide
lidocaine

36
Q

class 2

A

beta blockers

37
Q

how do class 2 work

A

inhibits dysrhythmias mediated by SNS
competes with endogenous catecholamines for receptor sites

38
Q

example of class 2

A

propanolol
metaprlol
esmolol

39
Q

how do class 3

A

slows repolarization and prolongs action potential

40
Q

examples of class 3

A

amiodarone
dofetilide
ibutilide

41
Q

class 4

A

calcium channel blockers

42
Q

how do class 4 drugs work

A

blocks calcium channel primaryilu in atria, sinus and AV node; depresses sinus AV condition and terminates tachys

43
Q

proarrythmic drugs

A

quindine
procaniamide
dofetilide
ibutilide

44
Q

cardiac output equation

A

heart rate x stroke volume

45
Q

stroke volume 3 components

contractility

46
Q

preload

A

volume

47
Q

afterload

A

resistance

48
Q

what can make afterload higher

A

vasoconstriction

49
