3370: CARDIAC MEDS Flashcards
Adensoine
Only used to tx SVT
SLOWS conduction through AV node; effectively terminates narrow complex reentry type dysrhythmias
Asystole for 1-3 seconds
Amiodarone
"slows rate" (converts rhythm more than controls rate) V-Tach Ectopic SVT WPW VFib Pulseless VTach
Atropine
Increases HR Bradycardia Asystole PEA <60bpm MAX of 3mg
Dilitiazem
Slows conduction rate w/o conversion of rhythm
A-Fib
A-Flutter
SVT refractory to Adenosine
Dopamine
Increases Rate, Contractility, and Systemic Vasoconstriction
Hypotension
Bradycardia
Epinephrine
Increases automaticity All cardiac arrests Bradycardia Anaphylaxis Severe Bronchoconstriction
Contraindication of Lasix
Given too fast may cause loss of hearing
Lidocaine
Slows ventricular depolarization rate Alternative to Amiodarone Ventricular Fibrillation Pulseless Ventricular Tachycardia Wide Complex Tachycardia Suppression of PVCs
Contraindication of Lidocaine
Acute Mental Confusion in the Elderly
Magnesium Sulfate
Used in cardiac arrests only if Torsades de Pointes or suspected hypomagnesemia ETOH abusers Thiazide Diuretic users Torsades with a pulse Dig Toxicity
Metoprolol
Slows HR
Narrow Complex Tachycardia refractory to Adenosine
MI
BP control
Contraindications for Metoprolol
Prolonged PR Interval
HR less than 60
Diastolic less than 90
Naloxone
reversal of opiates
Nitroglycerin
decreases preload, work load, and oxygen demand
Flumazeni
reversal of benzodiazepines
