| stroke | <neurology> A condition due to the lack of oxygen to the brain which may lead to reversible or irreversible paralysis. The damage to a group of nerve cells in the brain is often due to interrupted blood flow, caused by a blood clot or blood vessel bursting. Depending on the area of the brain that is damaged, a stroke can cause coma, paralysis, speech problems and dementia. (16 Dec 1997) |
| stroke output | <physiology> The amount of blood pumped out of one ventricle of the heart as the result of a single contraction. A measure of the effectiveness of ventricular contraction. (16 Dec 1997) |
| stroke volume | <physiology> The amount of blood pumped out of one ventricle of the heart as the result of a single contraction. A measure of the effectiveness of ventricular contraction. (16 Dec 1997) |
| stroke work index | A measure of the work done by the heart with each contraction, adjusted for body surface area; equal to the stroke volume of the heart multiplied by the arterial pressure and divided by body surface area; the normal stroke work index does not exceed 40 gram-meters per square meter. (05 Mar 2000) |
| dead-stroke | <mechanics> Making a stroke without recoil; deadbeat. <machinery> Dead-stroke hammer, a power hammer having a spring interposed between the driving mechanism and the hammer head, or helve, to lessen the recoil of the hammer and reduce the shock upon the mechanism.

| syphilitic stroke | <pathology> A stroke that occurs as a complication of a tertiary syphilis infection. The underlying cause is destruction of the carotid arteries which supply the brain. (27 Sep 1997) |
| abnormal heart chamber dimensions | <radiology> Left ventricular volume overload, left ventricular hypertrophy, right ventricular volume overload, right ventricular hypertrophy, fixed subvalvular aortic stenosis, hypoplastic left/right ventricle; common ventricle, congestive cardiomyopathy (12 Dec 1998) |
| Abrams' heart reflex | A contraction of the myocardium when the skin of the precordial region is irritated. (05 Mar 2000) |

| apex of heart | The blunt extremity of the heart formed by the left ventricle. See: apex beat. Synonym: apex cordis, vertex cordis. (05 Mar 2000) |
| armored heart | Calcareous deposits in the pericardium due to subacute or chronic pericarditis. Synonym: panzerherz. (05 Mar 2000) |
| armor heart | Extensive to complete calcification (rarely ossification) of the pericardium usually producing constrictive pericarditis. (05 Mar 2000) |
| artificial heart | A mechanical pump used to replace the function of a damaged heart, either temporarily or as a permanent prosthesis. (05 Mar 2000) |
| artificial heart valve | <cardiology> A synthetic or porcine (pigskin) valve surgically placed into the heart to replace a defective or malfunctioning valve. The aortic and mitral valves are the most frequently replaced with artificial valves. (27 Sep 1997) |
