Cardiovascular Agents Flashcards
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
cardiac dysrythmia with rapid uncoordinated contractions of atrial myocardium
Atrial Fibrillation
cardiac dysrythmia with rapid contractions of 200 to 300 BPM
Atrial Flutter
any deviation from the normal rate or pattern of the heartbeat
Cardiac Dysrhythmia (Arrhythmia)
action that decreases heart rate
Chronotropic Action
action that increases heart rate
Dromotropic Action
a condition in which the compensatory mechanisms of heartbeat fail and the peripheral and lung tissues are congested
Congestive Heart Failure (CHF)
action that increases myocardial contraction stroke volume
Inotropic Action
amount of blood in the ventricle at the end of diastole
Preload
peripheral vascular resistance
Afterload
return of cell membrane potential to resting after depolarization
Repolarization
Therapeutic Serum Level for Digoxin
0.8 to 2.0 ng/mL
urine output
Diuresis
excess calcium
Hypercalcemia
serum potassium excess
Hyperkalemia
elevated serum uric acid level
Hyperuricemia
sodium loss in the urine
Natiuresis
sodium-losing
Natiuretic
marked decrease in urine output
Oligouria
concentration
Osmolality
sodium-chloride losing
Saluretic
drug that inhibits the post-ganglionic functioning of the sympathetic nervous system
Sympatholytics
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
Signs & Symptoms of Digitalis Toxicity
confusion, delirium, anorexia, diarrhea, N&V, bradycardia, dysrhythmias, premature ventricular contractions, visual disturabances (cardiotoxicity)
