lidocaine analog

Question 3

disopyramide

Answer 3

class 1A Na channel blocker

heavy antimuscarinic effects

Question 4

propranolol

Answer 4

class 2 non selective beta blocker

for supraventricular and ventricular arrythmia cuased by SYM stimulation

can prevent V fib

Question 5

sotalol

Answer 5

class 3 K channel blocker

used for treatment of life threatining vent arrythmias

maintaining normal sinus rhythem in A fib

treatment of supraventricular and ventricular arrythmias in kids (less long term effects than amiodarone)

Question 6

quinidine

Answer 6

class 1A Na channel blocker

medium antimuscarinic effects

increases plasma digoxin, thrombocytopenia, alpha blockade

Question 7

metalic taste

same stuff as flecainide

Question 8

verapamil

Answer 8

class 4 Ca channel blocker

oral CCB - used for treatment of supraventricular arrythmias and for rate control in A fib
