Med Surg- Cardiac Med - Part 1 Study
Set Exam
Prodysrhythmia - Answer development of a new, or reappearance of an existing,
dysrhythmia when an antidysrhythmic drug is administered and the drug level is not a
toxic level
What cardiac med decreases impulse conduction in the atria, ventricles, and
His-Purkinje system - Answer Class I: Sodium channel blockers
What cardiac meds delay repolarization and are seen as a widened QRS and prolonged
QT interval on a ECG - Answer Class IA
- Disopyramide (Norpace)
- Procainamide
- Quinidine
What cardiac meds accelerate repolarization and have little to no effect on an ECG -
Answer Class IB
- Lidocaine
- Mexiletine
- Phenytoin (Dilantin)
What cardiac meds decrease impulse conduction and have pronounced prodysrhythmic
actions, widen QRS, and a prolong Qt interval - Answer Class IC
- Flecainide
- Propafenone (Rythmol)
What cardiac meds decrease automaticity of the SA node, slow impulse conduction in
AV node, reduce atrial and ventricular contractility and is seen as bradycardia,
prolonged PR interval, and AV block - Answer Class II: beta-adrenergic blockers
- esomolol (brevibloc)
- metoprolol (Lopressor)
- propranolol (Inderal)
what cardiac meds delay repolarization resulting in prolonged duration of action
potential and refractory period and is seen as a Prolonged PR an QT interval, widened
QRS, bradycardia on an ECG - Answer CLass III: Potassium channel blockers
, - amiodarone
- dofetilide (Tikosyn)
- Ibutilide (covert)
- Sotalol (betapace)
what cardiac meds decrease automaticity of the SA node, delay AV node conduction;
reduce myocardial contractility and is seen as bradycardia, prolonged PR interval, AV
block on an ECG - Answer Class IV: CCB
- diltiazem (adenocrad)
- verapamil
What are the other cardiac meds that cause decreased conduction though AV node,
reduce automaticity of the SA node, and is seen as prolonged PR interval, and AV
block? - Answer - adenosine (adenocard)
- Digoxin (Lanoxin)
What are the other cardiac meds that cause suppression of atrial dysrhythmias though
mechanism is unknown and is seen as a prolonged QT interval? - Answer Dronedarone
(Multaq)
What are the other cardiac meds that cause decreases impulse conduction through AV
node and is seen as AV block on a ECG. - Answer magnesium
Antiarrhythmic drugs are usually for - Answer tachyarrhythmias
What would we assess before giving cardiac drugs? - Answer Baseline ECG
VS
Heart a lung sound
Lab values
Electrolytes
Liver and kidney function
(Closely monitor ECG and VS especially BP & HR)
What drugs are class IA - Answer Disopyramide (Norpace)
Procainamide (Pronestyl)
Quinidine (Quinora)
What drugs are in class IB - Answer Lidocain (xylocain)
