Cardiovascular Flashcards
(20 cards)
Slow progressive accumulation of fatty plaques on the inner walls or arteries:
Atherosclerosis
A condition where veins and valves in the LE are damaged and cannot keep blood flowing toward the heart:
Chronic venous insufficiency- CVI
Aka- pulmonary heart disease. Hypertrophy of the right ventricle caused by the altered structure or function of the lungs:
Cor Pulmonale
The narrowing or blockage of the coronary arteries due to atheromatous plaques resulting in diminished blood flow:
Coronary artery disease (CAD)
Blood clot in one or more of the deep veins, usually in the LE’s:
Deep vein thrombosis - DVT
Aka- congestive heart failure. Heart cannot maintain a normal cardiac output to meet the body’s demands for blood and oxygen
Heart failure
Aka- heart attack. Blood flow through one or more of the coronary arteries is severely reduced or cut off completely:
Myocardial infarction - MI
Diseases of the aorta and peripheral arteries:
Peripheral artery disease
Damage to one or more of the hearts valves resulting in regurgitation or stenosis of blood flow:
Valvular heart disease
Dilation of a blood vessel:
Aneurysm
Transient pre cordial sensation of pressure or discomfort resulting from myocardial ischemia:
Angina
CHF term comes from blood backing up into the ______, ________, ________, and _________
Lungs, liver, LE’s, and abdomen
Hematocrit definition:
% of RBCs in the blood
Low vs. high hematocrit
Low- anemia, blood loss, vit/min deficiency
High- dehydration or polycythemia Vera
CHF term comes from blood backing up into the ______, ________, ________, and _________
Lungs, liver, LE’s, and abdomen
These nerves stimulate the heart to beat faster (chronotrophic effect)
Sympathetic
These nerves slow HR (chronotrophic effect)
Parasympathetic
P wave
Atrial depolarization
QRS complex
Ventricular depolarization and atrial repolarization
T wave
Ventricular repolarization
