| systolic pressure | <cardiology, physiology> The pressure exerted on the walls of the arteries during the contraction phase of the heart. Considered abnormally elevated if consistently over 150 mmHg. Systolic blood pressure varies with age, sex, size and relative condition. (27 Sep 1997) |
|---|---|
| systolic shock | The abnormally palpable impact, appreciated by a hand on the chest wall, of an accentuated first heart sound. (05 Mar 2000) |
| systolic thrill | A thrill felt over the precordium or over a blood vessel during ventricular systole. (05 Mar 2000) |
| systolic time intervals | See: electromechanical systole, left ventricular ejection time, preejection period. (05 Mar 2000) |
| systolic whoop | systolic honk |
| total end-systolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in systole. (05 Mar 2000) |
| end-systolic volume | The amount of blood in the ventricle at the end of the cardiac ejection period and immediately preceding the beginning of ventricular relaxation; a measurement of the adequacy of cardiac emptying, related to systolic function. (05 Mar 2000) |
| late apical systolic murmur | A murmur previously considered benign, or even extracardiac, with a possible relationship to pericardial disease; it often represents mitral insufficiency, often localised and of moderate severity but with propensity for developing bacterial endocarditis, and is frequently associated with systolic click and mitral prolapse (Barlow syndrome; a balloon or billowing mitral valve leaflet) often producing a click, murmur, or both, as it prolapses during systole into the left atrium. (05 Mar 2000) |
| accelerated idioventricular rhythm | A transient and intermittent type of arrhythmia with episodes lasting from a few seconds to a minute which usually occurs in patients with acute myocardial infarction or with digitalis toxicity. Suppressive therapy is rarely necessary because the ventricular rate is generally less than 100 beats per minute. (12 Dec 1998) |
| agonal rhythm | An idioventricular rhythm, characterised by unusually wide and bizarre ventricular complexes, often seen in moribund patients. (05 Mar 2000) |
| alpha rhythm | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
| atrioventricular junctional rhythm | The cardiac rhythm when the heart is controlled by the A-V junction (including node); arising in the A-V junction, the impulse ascends to the atria and descends to the ventricles, each at varying speeds depending on site of the pacemaker. Synonym: A-V junctional rhythm, nodal bradycardia, nodal rhythm. (05 Mar 2000) |
| A-V junctional rhythm | The cardiac rhythm when the heart is controlled by the A-V junction (including node); arising in the A-V junction, the impulse ascends to the atria and descends to the ventricles, each at varying speeds depending on site of the pacemaker. Synonym: A-V junctional rhythm, nodal bradycardia, nodal rhythm. (05 Mar 2000) |
| basic electrical rhythm | A slow wave of depolarisation of smooth muscle from the fundus to the pylorus that coordinates gastric peristalsis and emptying. (05 Mar 2000) |
| Berger rhythm | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
