Question 3

result of beta blockers**

bradycardia adverse effect

Answer 5

speed up the heart too much

asthmatic adverse effects if not

Answer 7

a selective beta blocker

Question 8

caution of beta blockers with

diltiazem (Cardizem)

Answer 11

see to decrease HR **; decrease number of times muscle contracts and to relax vessels; so vasodilating effect

Question 12

calcium channel blockers do what

calcium channel blockers used to treat

Answer 16

HTN, atrial fibrilliation, stable and variant angina

Question 17

CA blockers used for

hypotension; atrium fiber latrim (decrease impuluses through AV node); stable and varient angina (will open up vessels)

Question 18

“dipines”

Answer 18

peripheral vessel CA channel blockers - block CA from vessels = expand/vasodilate; also treats high bp or treatment of afib
