Q

Class 2 anti arrhythmic drugs

A

Beta blockers - depress funny current, repolarization time is slightly shortened because calcium is blocked from entry

Also reduce phase 0 in AV node cells

Q

Class 1a anti arrhythmic drugs

A

Quinidine- strong Na channel block, also blocks K channels prolonging repolarization - widening of QRS and longer QT interval

20
Q

Bretylium

A

Class 3 anti arrhythmic

21
Q

Epinephrine

A

Alpha and beta 1,2 agonist

22
Q

Norepinephrine

A

Alpha and beta 1 agonist

23
Q

Phenlyephrine

A

Alpha agonist

24
Q

Isoproterenol

A

Beta 1,2 agonist

25
Q

Dopamine

A

Inotropic agent
Neurotransmitter in the brain

Increase contractile force without increasing the heart rate

Can be given to peope with bad Kidney function- increase flow to kidneys

At higher doses effects alpha receptors causes vasoconstriction

26
Q

Dobutamine

A

Inotropic agent

27
Q

Propranolol

A

Beta 1,2 blocker

28
Q

Phentolamine

A

Alpha blocker- short acting

29
Q

Phenoxybenzamine

A

Alpha blocker- long acting

30
Q

Left anterior descending artery

A

Branches-
Diagonal branch

Both supply upper portion of left ventricle- anterior wall

31
Q

Left circumflex artery

A

Moves through atrioventricular groove

Supply lateral wall

32
Q

Right coronary artery

A

Branch: posterior descending artery

Supplies inferior wall

33
Q

Beta 1 receptor location

A

Heart

34
Q

Beta 2 receptor location

A

Vessels,

Bronchi

35
Q

Albuterol

A

Beta 2 agonist

36
Q

Ritodrine

A

Beta 2 agonist

37
Q

Metoprolol

A

Beta 1 antagonist

38
Q

Amphetamine

A

Increases norepinephrine output reverses release of norepinephrine carrier- normally pumps NE into presynapyic cell, now released

39
Q

Cocaine

A

Inhibits nE transporter back into cell out of synapse

40
Q

Normal pr interval

A

.12-.2 sec

3-5 small boxes

41
Q

Normal qrs interval

A

Less than .1 sec

Less than 2.5 boxes

42
Q

Qt interval

A

Corrected QT IS QT/ square root of RR Intercal in seconds

Normally less than .44 seconds

43
Q

Nitrates

A

Dilate vein so that more blood is in the veins and less returns to the heart- this lowers preload of heart

Can also vasodilator- increase o2 which gets to heart

Trigger smooth muscle to produce NO which causes vasodilation

44
Q

Inferior leads

A

II, III. Avf

45
Q

Anteroseptal leads

A

V1 and v2

46
Q

Anterior wall

A

V3 and v4

47
Q

Anterolateral wall leads

A

Leads v5, v6 I and avl
