Cardiac Drugs Quick Sheet!

Just a quick overview for the major cardiac/ACLS drugs as pertaining to adults. This is essentially what my flash cards would pertain! Get your AHA ACLS Manual here!

Digoxin

  • Action
    • Positive inotrope – increases the force of cardiac contraction
    • Decrease HR
    • Allow for more complete emptying of the ventricles, thus increasing CO
    • Decrease conduction through the AV node, reduce automaticity of the SA node
  • Indications
    • Heart failure
    • A-fib and A-flutter
    • Paroxysmal atrial tachycardia
  • Special Considerations
    • Monitor potassium levels
    • Count apical for 1 min prior to administration

Atropine

  • Action
    • An anticholinergic drug and increases the firing of the SA node by blocking the action of the vagus nerve.
    • Increases HR
  • Indications
    • 1st line for symptomatic bradycardia
  • Special Considerations
    • Anticholinergic S/E
    • Increases myocardial oxygen demand à be careful in presence of myocardial ischemia

Adenosine

  • Action
    • Antiarrhythmic that decreases conduction through the AV node
  • Indications
    • Paroxysmal Supraventricular Tachycardia
  • Special Considerations
    • Commonly causes a few seconds of asystole
    • Very short half-life (6-10 seconds)
    • Push FAST
    • Patient may feel “like they got punched in the chest”

Amiodarone

  • Action
    • Delay repolarization resulting in prolonged duration of action potential and refractory period
    • Class III Potassium Channel Blocker
    • Decreases heart rate and contractility
  • Indications
    • Pulseless V-fib or V-tach
    • Oral – Atrial fibrillation
  • Special Considerations
    • Do NOT use with cardiogenic shock or severe sinus bradycardia à may cause hypotension

Epinephrine

  • Action
    • Stimulate beta1 receptors à cardiac stimulation
    • Increased HR, CO, and contractility
  • Indications
    • Cardiogenic shock, Anaphylactic shock, Septic shock
    • Cardiac arrest, pulseless ventricular tachycardia, ventricular fibrillation, asystole
  • Special Considerations
    • Raises BP and increases HR à may cause myocardial ischemia, angina
    • May contribute to post-resuscitation myocardial dysfunction

Dopamine

  • Action
    • Positive inotropic
    • Increased myocardial contractility, increased automaticity, increased AV conduction, increased HR, CO, BP, MAP
  • Indications
    • Cardiogenic shock
    • 2nd line for symptomatic bradycardia
  • Special Considerations
    • Correct hypovolemia with volume replacement before using dopamine
    • DO NOT mix with Sodium Bicarb

Lidocaine

  • Action
    • Sodium channel blocker
  • Indications
    • V-fib, V-tach – with and without pulse
  • Special Considerations
    • *REMOVED from ACLS Guidelines*
    • Can cause toxicity!
