| shock wave lithotripsy | A method of fragmenting calculi. (05 Mar 2000) |
|---|---|
| short wave diathermy | Therapeutic elevation of temperature in the tissues by means of an oscillating electric current of extremely high frequency (10 to 100 million Hz) and short wavelength of 3 to 30 meters. (05 Mar 2000) |
| short-wave therapy | The use of focused short radio waves to produce local hyperthermia in an injured person or diseased body area. (12 Dec 1998) |
| square wave stimuli | Electrical stimulation in which the intensity of the current is brought suddenly to a given level and maintained at that level until it suddenly is cut off; this type of stimulus is particularly useful in obtaining a strength-duration curve. (05 Mar 2000) |
| delta wave | A premature upstroke of the QRS complex due to an atrial ventricular bypass tract as in WPW syndrome. Synonym: delta rhythm. (05 Mar 2000) |
| S wave | A negative (downward) deflection of the QRS complex following an R w; successive downward deflections within the same QRS complex are labelled S', S'', etc. (05 Mar 2000) |
| dicrotic wave | The second rise in the tracing of a dicrotic pulse. Synonym: recoil wave. (05 Mar 2000) |
| drift wave | <radiobiology> Oscillations in a magnetically-confined plasma arising in the presence of density gradients (such as at the plasma's surface). These resemble the waves that propagate at the interface of two fluids with different density in a gravitational field. (09 Oct 1997) |
| D wave | A positive or negative deflection in the electroretinogram occurring when a light stimulus is removed (off-response). (05 Mar 2000) |
| quarter-wave plate | <microscopy> A compensator giving a retardation of about 130 nm, and a phase shift of 1/4 ~, thus constituting a device used with a polarizer and analyser designed to produce circularly polarized light. (05 Aug 1998) |
| Q wave | The initial deflection of the QRS complex when such deflection is negative (downward). (05 Mar 2000) |
| overflow wave | The descending wave of the sphygmogram from the apex to the first anacrotic break. (05 Mar 2000) |
| theta wave | Brain waves in the electroencephalogram which have a frequency of 4 to 7 per second. They occur mainly in children but also in adults during periods of emotional stress. (12 Dec 1998) |
| tidal wave | The wave between the percussion wave and the dicrotic wave in the downward limb of the arterial pulse tracing. (05 Mar 2000) |
| electrocardiographic wave | <cardiology, physiology> A deflection of special shape and extent in the electrocardiogram representing the electric activity of a portion of the heart muscle. (05 Mar 2000) |
