Triphasic waveforms
WebApr 12, 2024 · The waveform is also defined by its monophasic, biphasic, or triphasic pattern. Triphasic patterns are found most often in the lower extremities. Using gray-scale technique, a significant atherosclerotic vascular lesion can be detected only by thickening of the vessel wall or segmental narrowing of the lumen (which usually represents plaque or ...

WebFour distinctive waveforms were identified. The unifying feature of the waveforms was an abrupt decline in flow velocity after the early systolic upstroke. This deceleration could be definitively located at mid systole by comparing the Doppler tracing with the synchronously recorded ECG tracing. WebTriphasic waves (TWs) are a distinctive, although non-specific EEG pattern, which are quite frequently encountered and sometimes difficult to interpret. Although initially considered pathognomonic of hepatic encephalopathy, TWs have been described in association with a large number of conditions.
