| diastolic blood pressure | The pressure exerted on the walls of the arteries when the heart is in the relaxation phase (diastole). Considered abnormally elevated if consistently over 90 mmhg. (27 Sep 1997) |
|---|---|
| diastolic murmur | A murmur heard during diastole. (05 Mar 2000) |
| diastolic pressure | The intracardiac pressure during or resulting from diastolic relaxation of a cardiac chamber; the lowest arterial blood pressure reached during any given ventricular cycle. (05 Mar 2000) |
| diastolic shock | The abnormally palpable impact, appreciated by a hand on the chest wall, of an accentuated third heart sound. (05 Mar 2000) |
| diastolic thrill | A thrill felt over the precordium or over a blood vessel during ventricular diastole. (05 Mar 2000) |
| early diastolic murmur | A murmur that begins with the second heart sound, as the murmur of aortic insufficiency. (05 Mar 2000) |
| total end-diastolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in diastole. (05 Mar 2000) |
| end-diastolic | 1. Occurring at the end of diastole, immediately before the next systole, as in end-diastolic pressure. 2. Interrupting the final moments of diastole, barely premature, as in end-diastolic extrasystole. (05 Mar 2000) |
| end-diastolic volume | The amount of blood in the ventricle immediately before a cardiac contraction begins; a measurement of cardiac filling between beats, related to diastolic function. (05 Mar 2000) |
| late diastolic murmur | A murmur heard at the end of ventricular diastole (during atrial systole if in sinus rhythm), usually due to obstruction at one of the atrioventricular orifices. Synonym: atriosystolic murmur, late diastolic murmur. (05 Mar 2000) |
