| VFP | ventricular filling pressure; ventricular fluid pressure |
|---|---|
| VFT | venous filling time; ventricular fibrillation threshold |
| ESWL | Extracorporeal Shock-Wave Lithotripsy - Ix for Gall Stone ... |
| CW | cardiac work; case work; cell wall; chemical warfare; chemical weapon; chest wall; children's ward; ... |
| CWD | cell wall defect; continuous-wave Doppler |
| y wave | The wave in the atrial and venous pulse curves reflecting rapid filling of the ventricles just after the atrioventricular valves open. (05 Mar 2000) |
|---|---|
| U wave | A positive wave following the T wave of the electrocardiogram. (05 Mar 2000) |
| fluid wave | A sign of free fluid in the abdominal cavity; percussion on one side of the abdomen transmits a wave that is felt on the opposite side. (05 Mar 2000) |
| free wave | <radiobiology> A wave (for example, electromagnetic) traveling in a homogeneous infinite medium (no boundary conditions). (09 Oct 1997) |
| longitudinal wave | <physics> Waves where the variation of the field is partially or totally in the direction of propagation (parallel to wavennumber, k [a vector]). Examples include sound waves and Langmuir waves. Contrasted with transverse waves, where the variation is perpendicular to the direction of propagation, such as light waves. (13 Nov 1997) |
