sinus rhythm
various mechanisms (pharmacodynamics) of antidysrhythmic medications - Answers :1.
blocks adrenergic stimulation of the heart
2. depresses myocardial excitability and contractility
3. decreases conduction velocity in cardiac tissue
4. increases recovery time (repolarization) in myocardium
5. suppresses automaticity
4 classes of antidysrhythmics - Answers :1. sodium channel blockers
2. beta blockers
3. meds that prolong repolarization
4. calcium channel blockers
action of sodium channel blockers - Answers :antidysrhythmic
decreases sodium influx into cardiac cells, decreasing conduction velocity, suppressing
automaticity, and increasing repolarization time
examples of sodium channel blocker - Answers :1. procainamide hydrochloride

abdominal pain, diarrhea
what rhythm is lidocaine given for - Answers :ventricular dysrhythmia, particularly v tach
with a pulse

routes of administration for sotalol hydrochloride - Answers :PO and IV
side effects of sotalol hydrochloride - Answers :1. bradycardia
2. heart failure
3. fatigue
4. dizziness
5. headache
6. palpitations
7. weakness
8. nausea and vomiting
9. dyspepsia
examples of drugs that prolong repolarization - Answers :1. adenosine
2. amiodarone
rhythm adenosine is used to treat - Answers :supraventricular tachycardia (SVT). can
turn into v-tach. patient will be very symptomatic
side effects and special considerations for adenosine - Answers :HAVE A CODE CART
