Triphasic signal

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 ...
