cardiovascular main
Term | Definition |
---|---|
systolic BP | ventricles contracting |
diastolic BP | ventricles relaxing |
sphygmomanometer | blood pressure cuff & gauge |
function | delivery system, circulates blood throughout body, carries waste in blood to be removed by other systems. |
Arteries | carry blood away from the heart |
Veins | carry blood to the heart |
epicardium | outer most layer of the heart |
myocardium | middle muscular layer of the heart |
endocardium | lines inner chambers and covers valves chamber (inner most layer) |
pericardium | membrane that surrounds the epicardium |
normal blood pressure | 120/80 |
atrial chambers | receive blood from body |
ventricular chambers | pump the blood to the lungs and body |
atrioventricular | Tricuspid and Bicuspid |
Semilunar | pulmonary and aortic |
pulmonary | right side of heart; from heart to lungs back to heart |
systemic | left side of heart; from heart to body cells and back to heart |
systolic BP | ventricles contracting |
diastolic BP | ventricles relaxing |
sphygmomanometer | blood pressure cuff & gauge |
head pulse | temporal |
neck pulse | carotid |
chest pulse | apical |
arm pulse | brachial |
waist pulse | femoral |
wrist pulse | radial |
back of knee pulse | popliteal |
feet pulse | dorsalis pedis |
pulse used for blood pressure | brachial |
pulse that requires stethoscope | apical |
most common pulse | radial |
Aneurysm | dilated blood vessel |
Angina | spasmodic chest pain caused by ischemia |
Cardiac Tamponade | compression of the heart due to excess fluid in pericardium |
Congestive Heart Failure (CHF) | reduced blood flow through the heart |
Coronary Artery Disease (CAD) | narrowing of the coronary arteries causing ischemia to myocardium |
Atherosclerosis | plaque build up in the arteries (plaque hardening) |
Arrhythmia | irregular heartbeat |
Bradycardia | condition of slow heart (rate) |
Tachycardia | condition of fast heart (rate) |
Shock | insufficient blood flow to the heart for normal body function |
Embolus | mass traveling in the blood vessel that causes an obstruction |
Thrombus | blood clot in the wall of a blood vessel |
Heart Murmur | abnormal heart sound |
Hypertension | high blood pressure |
Hypotension | low blood pressure |
Myocardial Infarction (MI) | tissue death in the heart |
Angiogram | uses a contrast dye to with a camera to monitor blood flow in vessels |
Cardiac Catheterization | placement of small catheter into artery to diagnose heart diseases |
Auscultation | using a stethoscope to listen to internal body sounds (heart, lungs, & bowels) |
Holter Monitor | portable machine worn to record cardiac rhythms |
Stress Test | procedure that tests how well heart is pumping |
Cardioversion | use of controlled electrical shock sent to the heart to restore a normal heart rhythm (planned procedure |
Defibrillation | uses an electrical shock to stop fibrillation of the heart in an emergency |
Pacemaker | electrical device implanted to stimulate the heart |
Heart Transplant | grafting a healthy donor heart to a patient |
Angiotensin-Converting (ACE) Inhibitor | used to treat hypertension |
Antianginal | used to prevent or alleviate spasmodic chest pain (angina) |
Anticoagulant | prevents blood clots |
Antihypertensive | counteracts high BP |
Antiarrhythmic | prevents or alleviates abnormal heart rhythms (arrhythmias) |
Beta Blocker | used to treat angina, hypertension, heart rhythm disorders, migraines, tremors and panic attacks |
Calcium Channel Blocker | dilates arteries and reduces BP so the heart can pump easier |
Diuretic | reduces excess water in body |
Hypolipidemic | reduces fats/cholesterol in the blood |
Thrombolytic | dissolve/breakdown clots |
Vasoconstrictor | narrows blood vessels to increase BP |
Vasodilator | widens blood vessels to decrease BP |
