Flashcards in Cardiovascular Agents Deck (26):
1

condition of acute cardiac pain caused by inadequate blood flow to the myocardium due to either plaque occlusions within or spasms of the coronary arteries

Angina Pectoris

2

cardiac dysrythmia with rapid uncoordinated contractions of atrial myocardium

Atrial Fibrillation

3

cardiac dysrythmia with rapid contractions of 200 to 300 BPM

Atrial Flutter

4

any deviation from the normal rate or pattern of the heartbeat

Cardiac Dysrhythmia (Arrhythmia)

5

action that decreases heart rate

Chronotropic Action

6

action that increases heart rate

Dromotropic Action

7

a condition in which the compensatory mechanisms of heartbeat fail and the peripheral and lung tissues are congested

Congestive Heart Failure (CHF)

8

action that increases myocardial contraction stroke volume

Inotropic Action

9

amount of blood in the ventricle at the end of diastole

Preload

10

peripheral vascular resistance

Afterload

11

return of cell membrane potential to resting after depolarization

Repolarization

12

Therapeutic Serum Level for Digoxin

0.8 to 2.0 ng/mL

13

urine output

Diuresis

14

excess calcium

Hypercalcemia

15

serum potassium excess

Hyperkalemia

16

elevated serum uric acid level

Hyperuricemia

17

sodium loss in the urine

Natiuresis

18

sodium-losing

Natiuretic

19

marked decrease in urine output

Oligouria

20

concentration

Osmolality

21

sodium-chloride losing

Saluretic

22

drug that inhibits the post-ganglionic functioning of the sympathetic nervous system

Sympatholytics

23

Stepped-Care Hypertension Approach

(1) Modify lifestyle (2) Diuretic or beta-blocker (3) Increase drug dose or add 2nd med from diff class (4) Add 2nd or 3rd drug or diuretic

24

Signs & Symptoms of Digitalis Toxicity

confusion, delirium, anorexia, diarrhea, N&V, bradycardia, dysrhythmias, premature ventricular contractions, visual disturabances (cardiotoxicity)

25

Five Categories of Diuretics

(1) Thiazides (2) loop diuretic (3) osmotic (4) Carbonic Anhydrase (4) Potassium Sparing

26

Categories of Antihypertensives

(1) diuretics (2) sympatholytics (3) direct-acting arteriolar vasodilators (4) ACE inhibitors (5) angiotension II receptor blockers (ARBs) (6) calcium channel blockers
