ADENOSINE
CLASS |
Endogenouse nucleoside
(occurs naturally in all cells of the body) |
|
|
Adenosine
Action |
*slows electrical conduction through AV node, inhibits re-entry pathway, converting SVT to NSR
*onset= withing 30sec. ; duration 1 to 2 minutes |
|
|
adenosine
Indications |
SVT
|
|
|
Adenosine
Contraindications |
*2nd and 3rd degree heart block
*sick sinus syndrome |
|
|
Adenosine
Side Effects |
*SOB/Dyspnea; may cause bronchospasm in asthma pt's "BHPO"
*Chest pressure / palitations; may be acute in some pt's *Mild Hypotension (decreased peripheral vascular resistance) *nausea *Trannsient arrhythmias; (bradycardias, AV blocks, sinus pause, ventricular ectopy) transient usually self limiting |
|
|
Aspirin
Class |
Salicylate
|
|
|
Aspirin
Action |
*Inhibits the natural tendency for platelets to accumulate inside injured or occluded cardiac arteries therby promoting better blood flow through vessels to better perfuse heart
*onset 15 to 30 minutes; duration Days |

*GI upset (indigestion, N/V, Epigastric PN, heartburn)
*Occult bleeding |
|
|
Atropine
Class |
Anticholinergic
|
|
|
Atropine
Action |
*Competes with acetylcholine for receptors blocking PNS resopnse to SA & AV nodes
*Increases heart rate by increasing electrical conduction through heart *Inhibits secreations by decreasing PNS effect on bronchial, salivary, sweat, and GI glands *onset= IV 2-4 min, Duration 2-6 hrs |
|
|
