| random waves | Wave's in the electroencephalogram which occur paroxysmally and asynchronously. (05 Mar 2000) |
|---|---|
| microelectric waves | That portion of the electromagnetic spectrum lying between uhf (ultrahigh frequency) radio waves and heat (infrared) waves. Microwaves are used to generate heat, especially in some types of diathermy. They may cause heat damage to tissues. (12 Dec 1998) |
| high-energy shock waves | Compression waves of large amplitude, across which density, pressure, and particle velocity change drastically. (12 Dec 1998) |
| sonic waves | Audible sound wave's, as distinguished from ultrasonic wave's. (05 Mar 2000) |
| supersonic waves | See: supersonic. (05 Mar 2000) |
| Traube-Hering waves | Slow oscillations in blood pressure usually extending over several respiratory cycles; related to variations in vasomotor tone; rhythmical variations in blood pressure. Synonym: Traube-Hering waves. (05 Mar 2000) |
| upper hybrid waves | <radiobiology> Similar to lower hybrid waves, but at a higher frequency. Not truly propagating waves, but plasma oscillations. (09 Oct 1997) |
| fibrillary waves | The waves of atrial flutter usually best seen in ECG leads 2, 3, and AVF. (A small f indicates atrial fibrillation). Synonym: fibrillary waves, fibrillatory waves, flutter-fibrillation waves. (05 Mar 2000) |
| fibrillatory waves | The waves of atrial flutter usually best seen in ECG leads 2, 3, and AVF. (A small f indicates atrial fibrillation). Synonym: fibrillary waves, fibrillatory waves, flutter-fibrillation waves. (05 Mar 2000) |
| flat top waves | Activity in the electroencephalogram having a pattern suggesting a flat top; these wave's are often found in temporal lobe discharges. (05 Mar 2000) |
| flutter-fibrillation waves | The waves of atrial flutter usually best seen in ECG leads 2, 3, and AVF. (A small f indicates atrial fibrillation). Synonym: fibrillary waves, fibrillatory waves, flutter-fibrillation waves. (05 Mar 2000) |
| F waves | The waves of atrial flutter usually best seen in ECG leads 2, 3, and AVF. (A small f indicates atrial fibrillation). Synonym: fibrillary waves, fibrillatory waves, flutter-fibrillation waves. (05 Mar 2000) |
| lower hybrid waves | <physics> Electrostatic ion oscillations at a frequency intermediate to the electron extraordinary wave (high frequency) and the magnetosonic wave (low frequency). (09 Oct 1997) |
