important cardiac drug info Flashcards
sodium channel blockers
neg chronotropic
neg dromotropic
procainamide (pronestyle)
1a (ventricular arrhythmias) *stable ventricular tachy *premature ventricular contractions *ventricular fibrillation (Supraventricular Tachy) *PSVT *PAT *Junctional tachs *atrial flutter and fibrillation
action of procainamide (pronestyle)
slows conduction
negative inotrope
decreases myocardial excitability
adverse effects of procainamide (pronestyle)
myocardial depression
prolongs duration of QRS, QT interval, AV conduction
Hypotension if given too fast IV
labs for procainamide (pronestyle)
platelets
administration of procainamide (pronestyle)
bolus 50-100 mg
IV SLOW over 5 minutes
Quinidine Norpase
positive anticholinergic
positive chronotropic
digitilize
give 3 doses of dig for therapeutic blood levels
Quinidine Norpase action
slows conduction through cardiac tissue
used for atrial flutter or fibrillation to maintain sinus rhythm
what should you do before administering Quinidine Norpase
digitilize first
adverse effects of Quinidine Norpase
diarrhea
thrombocytopenia
will increase digoxin levels
nursing considerations for Quinidine Norpase
baseline QT interval
monitor platelets
Lidocaine/xylocaine
anesthetizes myocardium
negative inotropic
negative dromotropic
Lidocaine/xylocaine administration
IV push 1-2 minutes
0.5 - 1 mg/kg bolus IV (NO PIGGYBACK)
MAKE SURE PLAIN/NO ADDITIVES
use infusion pump, do not mix with other drugs
Lidocaine/xylocaine
PVC’s -
Ventricular tachycardia
Lidocaine/xylocaine therapeutic level
1.5 to 6 ug/ml
Lidocaine/xylocaine adverse effects
paresthesias
confusion
crosses blood/ brain barrier
Class 1c drugs
most potent class I agents
PVCS
VT
negative dromotropic
Flecanamide/Rythmol
*POTENT* used if all other meds fail ventricular arrythmias rhythms a fib a flutter sever svt
side effects of flecanamide/rythmol
Chf because of negative inotropic effect
CHF, arrythmias
Beta Blockers
neg. chronotropic
neg. inotropic
neg. dromotropic
beta blockers used for
MI’s
HTN
can be used for arrythmias
prolong life
administration of Beta Blockers
IV or PO
Block Beta 1
