Chapter 9 Cards
Medical Terminology: Creative Study Assignment - Chapter 9
| Term | Definition |
|---|---|
| angi/o | vessel |
| coron/o | circle or crown |
| phleb/o | vein |
| sphygm/o | pulse |
| varic/o | swollen, twisted vein |
| valves of the veins | valves located at intervals within the lining of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart |
| diastole | to expand; period during the cardiac cycle (complete heart beat) when blood enters the relaxed ventricles from the atria |
| systole | to contract; period during the cardiac cycle (complete heart beat) when the heart is in contraction and blood is ejected through the aorta and the pulmonary artery |
| Purkunji fibers | fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract |
| depolarization | change of a myocardial cell from a polarized (resting) state to a state of contraction (de = not; polarization = resting) |
| normal sinus rhythm (NSR) | regular rhythm of the heart cycle stimulated by the SA node (average rate of 60–100 beats/minute) |
| aneurysm | a widening; a bulging of the wall of an artery caused by a congenital defect or acquired weakness |
| dissecting aneurysm | a split or tear of the arterial wall |
| atheromatous plaque | a swollen area within the lining of an artery caused by the buildup of fat (lipids) |
| ischemia | decreased blood flow to tissue caused by obstruction or constriction of a blood vessel; to hold back blood |
| coarctation of the aorta | narrowing of the descending portion of the aorta, resulting in a limited flow of blood to the lower part of the body |
| secondary hypertension | high blood pressure caused by the effects of another disease (e.g., kidney disease) |
| deep vein thrombosis (DVT) | formation of a clot in a deep vein of the body, occurring most often in the femoral and iliac vein |
| angiography | process of x-ray imaging a blood vessel after injection of contrast dye, most commonly after catheter placement |
| left heart catheterization | x-ray imaging of the left ventricular cavity and coronary arteries |
| right heart catheterization | measurement of oxygen saturation and pressure readings of the right side of the heart |
| cardiac output (CO) | measurement of the amount of blood ejected per minute from either ventricle of the heart |
| ejection fraction | measurement of the volume percentage of left ventricular blood ejected with each contraction |
| transesophagealechocardiogram (TEE) | echocardiogram of the heart after placement of an ultrasonic transducer at the end of an endoscope inside the esophagus |
| anastomosis | the joining of two blood vessels to allow flow from one to the other; opening |
| endarterectomy | surgical removal of the lining of an artery to clear a blockage caused by a clot or atherosclerotic plaque buildup |
| defibrillator | device that delivers the electrical stimulus in defibrillation |
| antianginal | drug that dilates coronary arteries, restoring oxygen to the tissues to relieve the pain of angina pectoris |
| cardiotonic | drug that increases the force of myocardial contractions in the heart; commonly used to treat congestive heart failure (CHF) |
| hypolipidemic | drug that reduces serum fat and cholesterol |
