(Cardiovascular System)
| Question | Answer |
|---|---|
| ather/o | fatty (lipid) paste |
| phleb/o | vein |
| varic/o | swollen, twisted vein |
| epicardium | membrane forming the outer layer of the heart |
| pericardial cavity | fluid-filled cavity between the pericardial layers |
| bicuspid valve | heart valve between the left atrium and the left ventricle (cuspis = point); also called the mitral valve |
| aorta | large artery that is the main trunk of the arterial system branching from the left ventricle |
| systemic circulation | circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues |
| 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 |
| atrioventricular (AV) node | neurological tissue in the center of the heart that receives and amplifies the conduction of impulses from the SA node to the atrioventricular bundle (bundle of His) |
| polarization | resting; resting state of a myocardial cell |
| normal sinus rhythm (NSR) | regular rhythm of the heart cycle stimulated by the SA node (average rate of 60-100 beats/minute) |
| arteriosclerosis | thickening, loss of elasticity, and calcification (hardening) of arterial walls |
| diaphoresis | profuse sweating (perspiration) |
| infarct | a localized area of necrosis (dead tissue cells) caused by ischemia resulting from occlusion of a blood vessel; to stuff into |
| anastomosis | joining of two blood vessels to allow flow from one to the other |
| valvuloplasty | surgical repair of a heart valve |
| antherectomy | excision of atheromatous plaque from within an artery utilizing a device housed in a flexible catheter that selectively cuts away or pulverizes tissue buildup |
| cardioversion | restoration of a fast of irregular heart rate to a normal rhythm, either by pharmaceuticals means or by delivery of electrical energy |
| Angiotensin-converting enzyme (ACE) inhibitors | drug that suppresses the conversion of angiotensin in the blood by the angiotensin-covering |
| anticoagulant | drug that prevents clotting of the blood; commonly used in the treatment of thrombophlebitis and myocardial infarction |
| Beta Blockers | agents that inhibit responses to sympathetic adrenergic nerve activity causing a slowing of electrical conduction and heart rate and a lowering of the pressure within the walls of the vessels; used to treat angina pectoris and hypertension |
| Vasodilators | drugs that cause dilation of the blood vessels, thereby increasing blood flow |
| ACS | acute coronary syndrome |
| CXR | chest x-ray |
| ICD | implantable cardioverter-defibrillator |
| PET | positron emission tomography |
| STAT | immediately |
| TPA | tissue plasminogen activator |
| arrhythmia | any of several kinds of irregularity or loss of rhythm of the heartbeat |
