Pulse wave velocity
= Pulse wave velocity
{title2=$c_p=L/\Delta t$}
The propagation speed inferred from an effective path distance and the travel-time difference of corresponding features in two arterial waveforms. Path definition, synchronized timing and reflections matter; a pulse peak need not track an unchanged waveform.<2024 Recommendations for Validation of Noninvasive Arterial Pulse Wave Velocity Measurement Devices>[Pressure-waveform acquisition and transit-time estimation]{ref}
