WebApr 14, 1999 · This signal is described as triphasic. The typical waveform generated has a mountain range appearance (Figure 2). Elderly people commonly have a biphasic signal. This characteristically has two parts: the forward flow component at systole, followed by a second forward flow in diastole. This is a ‘normal’ signal; it occurs with ageing and is ... WebMar 19, 2024 · A normal arterial Doppler signal in a lower extremity artery will have a triphasic signal with a brisk systolic upstroke ( Fig. 26.4A ). The first phase, with antegrade acceleration and deceleration, is due to contraction of the left ventricle ( Fig. 26.4B–E ).
