| 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) |
