mon vitals and Elytes, tox *seiz, confusion, stop if widening of QRS
End in what?
What does it treat besides dysrhythmias?
Beta 1-receptors in heart
Beta 2-receptors in lungs
How common a med?
How does it work and where?
Result is it _________myo contractility
beta blockers- HTN, MI, dysrhythmias
Most common cardiac med
slows HR and conduction velocity through AV
Beta adrenergics Blockers- treat what? end in what?
Metoprolol (Lopressor, toprolol)
How is it good in an acute MI, monitor what? How given at first and how given later? Don't give below __bpm
How good in angina? How long given weekly for angina?
When given w multiple CV meds: multiple antihypertensives can cause severe____in BP
Combined with dig may cause_____
give w food or not?
can pt stop suddenly?
HTN, MI, antidysrhythmics, angina (weekly till it goes away)
Metoprolol (lopressor, toprolol)
Early intervention, IV push q 2-5 min, monitor vitals every 2-5min, then start PO
weekly dose till angina free
yes, better absorption
BBs Propanolol (Inderal)
Treats dysrhythmics and also____ and _____
On own or combined w other dysrhythmics, usually?
K+ channel blockers
How do they work?
Can they cause serious SEs? Amiodarone (cordarone)
tx of _______ ________
half life long or short?
block K+ ions channels in myo cells and lengthens resting stage of myo cell
w caution, yes, bradycaria, hypotension, hepatic dysfunction, photosensitivity
AV block, brady, arrhyth, HF, hypotension, headache, insomnia, photosensitivity, ab discomfort
Primarily for ____
How does it work?
________ _______of SA node
____ ____ through AV node
______ ____ in myo cells
Excessive levs cause _____ ______
Must take _________ one full min prior to giving
HF, also for arrhythmias
decreases automaticity of SA node
slows conduction through AV node
Inc contractility in myocardial cells
excessive levels cause serious dysrhythmias
(interacts w lots of meds, monitor drug levels, more so w hypoK+)
SEs arrhythnmias, HF, hypotenstion, anorex, hyperKalemia
Meds for angina, MI?
Give ___ first nitrates- Venous dilation decreases______
arterial dilation decreases _______
Dilates and relaxes spasms in ______
short acting long acting or both? Morphine- schedule ___
how does it help? Dilates______
O2,Nitrates, B Blockers, Ca_ blockers, thrombolytics (anticoags), morphine, antiplatelets,
- give first!!
Relaxes both arterial and venous smooth muscle.
Venous dilation decreases preload.
Arterial dilation decreases afterload. Decreases BP
B Blockers, Ca_ blockers, thrombolytics, antiplatelets
