Does pulse Doppler ultrasound measurement of vascular natural frequency accurately measure central artery elasticity compared to established pulse pressure wave velocity techniques?
Pulse Doppler ultrasound measurement of vascular natural frequency is a novel and potentially valid technique for measuring central artery elasticity, offering advantages for assessing deeply set central arteries.
Trevor Tucker (2026) conducted an observational in Cardiovascular diseases. Pulse Doppler ultrasound measurement of vascular natural frequency vs. Pulse pressure wave velocity (PWV) was evaluated on Match between measured arterial pulse flow response characteristics and those predicted by physical relationships. Pulse Doppler ultrasound measurement of vascular natural frequency matched established pulse pressure wave velocity measurements for determining central artery elasticity.
