| Aneurysm | A localized abnormal dilation of a blood vessel, usually an artery, caused by weakness of the vessel wall; may eventually burst |
| Arrythmia | Any abnormality in the rate or rhythm of the heart beat “without rhythm” |
| Fibrillation | Spontaneous, quivering, and ineffectual contraction of the muscle fibers, as in the atria or the ventricles |
| Cyanosis | Bluish discoloration of the skin caused by lack of oxygen |
| Edema | Swelling of body tissues caused by the presence of excess fluid, causes include cardiovascular disturbances, kidney failure, inflammation, and malnutrition |
| Embolus | A mass carried in the circulation. Usually a blood clot, but may also be air, fat, bacteria, or other solid material from within or from outside the body. |
| Thrombus | A blood clot that forms within a blood vessel (root: thromb/o) |
| Endocardium | Thin membrane that lines the chambers of the heart and covers the valves. (Innermost Layer) |
| Epicardium | The thin outermost layer of the heart wall |
| Myocardium | The thick middle layer of the heart wall composed of cardiac muscle |
| Pericardium | The fibrous sac that surrounds the heart |
| Hypertension (HTN) | A condition of higher than normal blood pressure; essential (primary, idiopathic) hypertension has no known cause |
| Hypotension | Lower than normal blood pressure |
| Infarct | An area of localized tissue necrosis (death) resulting from blockage or narrowing of the artery that supplies the area |
| Ischemia | Local deficiency of blood supply caused by circulatory obstruction (root: hem/o) |
| Perfusion | The passage of fluid, such as blood, through an organ or tissue |
| Regurgitation | A backward flow, such as the backward flow of blood through a defective valve |
| sphygmomanometer | Instrument for determining arterial blood pressure (root: sphygm/o means pulse) Blood pressure apparatus or cuff |
| Stenosis | Constriction or narrowing of an opening |
| Syncope | Temporary loss of consciousness due to inadequate blood flow to the brain (Fainting) |
