| A | B |
|---|
| cardiotonics | drugs increase efficiency improve contraction heart |
| sympathetic nervous system increase | epinephrine - norepinephrine |
| inotropic agents | causes heart to beat more forcefully |
| chronotropic agents | effects rate of heart beat |
| dromotropic agents | slows conduction down |
| L ventricle dysfunction causes | pulmonary problems |
| R ventricle dysfunction causes | vein distension - swollen ankles |
| digoxin overall | narrow therapeutic window, rapid onset, short duration |
| digoxin - cardiotonics family how do they work | increase cardiac output - increase force of contraction |
| digoxin adverse reactions | arrhythmias, h/a weakness drowsy, gi upset |
| toxic digoxin S & S | green/yellow halo hypotension main problem |
| digoxin teachings | take pulse, wt gain, green/yellow halo, vomit nausea |
| lab tests for digoxin | renal/hepatic, ekg, cbc electrolyte |
| digitalization | starting therapy - loading dose |
| normal digoxin levels | 0.5 - 2 nanograms |
| antiarrhythmic what is it | irregularity in heart rate |
| lidocaine - how does it work | slows down heart and allows conduction to begin |
| antidote for digoxin | digibind |
| dixogin used for | Heart failure |
| cardiotonics aka | cardiac glycosides digitalis glycosides |
