drugs Flashcards
treatments for SVT?
vagal maneuvers, adenosine, calcium channel blockers, beta blockers, procainamide, amiodarone, digoxin, rhythmol, cardioversion (consider anticoagulant)
treatment for vtach with a pulse?
lidocaine, procainamide, amiodarone, magnesium, cardioversion
what rhythms would you consider debrillation?
VT with no pulse and vfib
treatment for sinus brady
atropine
treatment for sinus pause/arrest, junctional escape, ventricular escape, AV block, asysytaole?
pacemaker
what does positive inotropic effect mean? neg?
inc myocardial contractility and dec
what does positive chronotropic effect mean? neg?
inc heart rate and dec
what does positive dromotropic effect mean? neg?
positive - enhanced conduction thru AV node and neg is delayed conduction through AV node
what types of properties do antiarrythmics have?
neg chronotropic - dec heart rate, positive or neg inotropic (contractility), neg dromotropy (dec conduction through AV node), depress automaticity, reduces myocardial oxygen consumption, suppressed PVCs, suppress re-entry activity, vagolytic, may elevate the the threshold for VF
class 1 of antiarrythmics ar what drugs?
sodium blockers (lidocaine, procainamide, propaferone)
class II of antiarrythmics?
beta blockers (internal, metoprolol, esmolol
class III of antiarrythmics?
potassium blockers (amiodarone, sataolol)
class IV of antiarrythmics?
ca cannel blockers (verapamil, dilimiazem)
class V of antiarrythmics?
dig, adenosine, magnesium
what types of meds block sympathetic stimulation? what doe they do?
beta blockers. beta 1 dec HR, AV node conduction and contractility and beta 2 causes bronchoconstriction and pulmonary vascular vasoconstriction
