A comparison was made between the AB ratio, resistance index (RI), and pulsatility index (PI 1, calculated from tracings obtained by pulsed Doppler (PD) and continuous wave ( C W ) Doppler devices in 14 uncomplicated singleton pregnancies. The AB ratio, RI, and PI were a slightly higher for the CW D
## Abstract ## __Purpose:__ To assess sympathetic vasomotor activity and its changes with age, using pulsed wave Doppler ultrasound. ## __Methods:__ We recruited 20 young adults (24β37 years old) and 20 older individuals (60β81 years old). Pulsed wave Doppler ultrasound was applied over the righ
