Terms | Definitions |
|---|---|
 afterload | the pressure that must be exceeded before ejection of blood from the ventricles can occur |
| amplitude | indicative of arterial blood pressure; estimated on the difference of pressure exerted by the fingers to occlude and then reopen the arterial pulse. |
| arrhythmia | an abnormal rate of muscle contractions in the heart |
| automaticity | The ability of the heart to generate and conduct electrical impulses on its own. |
| bruit | abnormal sound; blowing, swishing, or murmuring sound caused by turbulent blood flow; heard during auscultation |
| diastole | period when the heart relaxes and the ventricles fill with blood; in blood pressure measurements, the "bottom" value represents diastole |
| mediastinum | the part of the thoracic cavity between the lungs that contains the heart and aorta and esophagus and trachea and thymus |
| murmur | abnormal heart sound caused by improper closure of the heart valves |
| precordium | anterior surface of the body overlying the heart and great vessels |
| preload | Volume of blood that fills the heart and stretches the heart muscle fibers during its resting phase (volume of blood in ventricles at end of diastole, just prior to contraction) |
| systole | cardiac phase during which the ventricles contract and eject blood into the pulmonary and circulatory systems |
| arteriosclerosis | thickening and hardening of the walls of the arteries, can also decrease the blood supply to the brain and cause a decrease in mental abilities |
| atherosclerosis | a stage of arteriosclerosis involving fatty deposits (atheromas) inside the arterial walls |
| capacitance vessels | the term for veins because they have the ability to stretch. they have a large diameter and are more distensible to hold more blood. this reduces stress on the heart. |
| Homan's sign | aching or cramping pain in the calf felt with passive dorsiflexion of the foot; sign of thrombosis of deep veins in the calf |
| ischemia | insufficient blood flow to an area |
| pulse | pressure of the blood felt against the wall of an artery as the heart contracts or beats |
| varicose veins | distended or tortuous veins usually found in the lower extremities |
