| cannon wave | An exaggerated A wave in the jugular pulse caused by right atrial contraction occurring after ventricular contraction has closed the tricuspid valve, as in ventricular premature beats and in complete A-V block. (05 Mar 2000) |

| radio wave | <physics> Electromagnetic radiation with wavelengths of 300 millimetres or longer (even up to several kilometres). Radiation of this type is used to broadcast radio and television signals, and has frequencies up to thousands of megahertz (or one gigahertz). (09 Oct 1997) |
| recoil wave | The second rise in the tracing of a dicrotic pulse. Synonym: recoil wave. (05 Mar 2000) |
| V wave | <cardiology, physiology> A large pressure wave visible in recordings from either atrium or its incoming veins, normally produced by venous return but becoming very large when blood regurgitates through the A-V valve beyond the chamber from which the recording is made. (05 Mar 2000) |
| retrograde P wave | The P wave pattern in the electrocardiogram representing retrograde depolarisation of the atria, the impulse spreading from the A-V junction or the lower atrium upward. (05 Mar 2000) |
| percussion wave | The main positive wave of an arterial pulse tracing. (05 Mar 2000) |
| R wave | The first positive (upward) deflection of the QRS complex in the electrocardiogram; successive upward deflections within the same QRS complex are labelled R', R'', etc. (05 Mar 2000) |
| wave | 1. An advancing ridge or swell on the surface of a liquid, as of the sea, resulting from the oscillatory motion of the particles composing it when disturbed by any force their position of rest; an undulation. "The wave behind impels the wave before." (Pope) 2. <physics> A vibration propagated from particle to particle through a body or elastic medium, as in the transmission of sound; an assemblage of vibrating molecules in all phases of a vibration, with no phase repeated; a wave of vibration; an undulation. See Undulation. 3. Water; a body of water. "Deep drank Lord Marmion of the wave." "Build a ship to save thee from the flood, I 'll furnish thee with fresh wave, bread, and wine." (Chapman) 4. Unevenness; inequality of surface. 5. A waving or undulating motion; a signal made with the hand, a flag, etc. 6. The undulating line or streak of luster on cloth watered, or calendered, or on damask steel. 7. A swelling or excitement of thought, feeling, or energy; a tide; as, waves of enthusiasm. <physics> Wave front See Undulatory theory, under Undulatory. Origin: From Wave,; not the same word as OE. Wawe, waghe, a wave, which is akin to E. Wag to move. See Wave. Source: Websters Dictionary (01 Mar 1998) |
| wave analyzer | An apparatus that assesses a complex mixture of wave forms by separating out their component frequencies and displaying their distribution. (05 Mar 2000) |
| wave form | The form of a pulse; e.g., an arterial pressure or displacement wave; or of the pacemaker pulse as demonstrated on the oscilloscope under a specified load. Synonym: waveshape. (05 Mar 2000) |
| wave number | <microscopy> The number of waves or cycles of light flux or radiant energy, measured through a distance of 1 cm. (05 Aug 1998) |
| plane wave | <microscopy> Wave in which wavefronts are parallel to a plane normal to the direction of propagation. (05 Aug 1998) |
| plasma wave | <physics> A disturbance of a plasma away from equilibrium, involving oscillations of the plasma's constituent particles and of an electromagnetic field. Plasma waves can propagate from one point in the plasma to another without net motion of the plasma. (09 Oct 1997) |
| compression wave | <radiobiology> Waves where the quantity which oscillates is the density of the medium, that is the medium at a given point alternately compresses and expands. Low-amplitude compression waves in air or water are commonly known as sound waves, shock waves are a high-amplitude form. Synonym: density wave. (13 Jan 1998) |
| postextrasystolic T wave | The modified T wave of the beat immediately following an extrasystole. (05 Mar 2000) |
