| tachometer | An instrument for measuring the velocity, or indicating changes in the velocity, of a moving body or substance. Specifically: An instrument for measuring the velocity of running water in a river or canal, consisting of a wheel with inclined vanes, which is turned by the current. The rotations of the wheel are recorded by clockwork. An instrument for showing at any moment the speed of a revolving shaft, consisting of a delicate revolving conical pendulum which is driven by the shaft, and the action of which by change of speed moves a pointer which indicates the speed on a graduated dial. <physiology> An instrument for measuring the velocity of the blood; a haematachometer. Origin: Gr. Swiftness, speed (fr. Quick): cf. F. Tachometre. Source: Websters Dictionary (01 Mar 1998) |

| tachy- | Rapid. Origin: G. Tachys, quick (05 Mar 2000) |
| tachyarrhythmia | <cardiology> A tachycardia associated with an irregularity in the normal heart rhythm. Origin: Gr. Rhythmos = rhythm (18 Nov 1997) |
| tachyauxesis | Type of growth in which a part grows more rapidly than the whole. Origin: tachy-+ G. Auxo, to increase (05 Mar 2000) |
| tachybradycardia syndrome | <syndrome> Alternate rapid and slow cardiac rates that may represent any rhythm disturbances in any combination usually related to sinus node disease. Synonym: tachybradycardia syndrome. (05 Mar 2000) |
| tachycardia | <clinical sign> The excessive rapidity in the action of the heart, the term is usually applied to a heart rate above 100 per minute and may be qualified as atrial, junctional (nodal) or ventricular and as paroxysmal. Origin: Gr. Kardia = heart (18 Nov 1997) |
| tachycardia en salves | Short runs of paroxysmal tachycardia of the Gallavardin type. Compare: Gallavardin's phenomenon. Origin: Fr. Tachycardia in salvos (05 Mar 2000) |
| tachycardia exophthalmica | Rapid heart action occurring as one of the symptoms of exophthalmic goiter. (05 Mar 2000) |
| tachycardia window | In paroxysmal tachycardia of the reentry type, the interval of time (the window) between the earliest and latest premature activation that can excite the paroxysm. (05 Mar 2000) |
| tachycardia, atrioventricular nodal reentry | A tachycardia characterised by rates between 150 and 250 beats per minute and a qrs complex of supraventricular origin. (12 Dec 1998) |
| tachycardia, ectopic atrial | A tachycardia originating in the atrial myocardium and characterised by rates between 135 and 175 beats per minute. (12 Dec 1998) |
| tachycardia, ectopic junctional | A tachycardia arising in the conduction tissues surrounding the atrioventricular node. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication. The rate may range from 140 to 250 beats per minute. (12 Dec 1998) |
| tachycardia, paroxysmal | Condition marked by attacks of rapid action of the heart having sudden onset and cessation. (12 Dec 1998) |
| tachycardia, paroxysmal atrial | Bouts of rapid, regular heart beating originating in the atrium (upper chamber of the heart). Often due to abnormalities in the av node relay station that lead to rapid firing of electrical impulses from the atrium which bypass the av node under certain conditions. These conditions include alcohol excess, stress, caffeine, overactive thyroid or excessive thyroid hormone intake, and certain drugs. Pat is an example of an arrhythmia where the abnormality is in the electrical system of the heart, while the heart muscle and valves may be normal. (12 Dec 1998) |
| tachycardia, sinoatrial nodal reentry | A tachycardia arising from the sinus node region and characterised by rates between 115 and 140 beats per minute. It is paroxysmal rather than constant. (12 Dec 1998) |

| tachistoscope |
A tachistoscope is a device that displays (usually by projecting) an image for a specific amount of time. It can be used to increase recognition speed or to show something too fast to be consciously recognized. The actual tachistoscopes used a slide or transparency projector equipped with the mechanical shutter system typical of a camera. The slide is loaded, the shutter locked open, and focusing and aligment are adjusted, then the shutter is closed. ...
