Pulsed Wave Doppler Ultrasound Is Useful to Assess Vasomotor Response in Patients with Multiple System Atrophy and Well Correlated with Tilt Table Study
Figure 2
The comparisons of hemodynamic variables between MSA patients and healthy controls. Regarding SVR, MSA patients had (a) lower HR elevation and (b) a prolonged SVR latency. As for the tilt table study, MSA patients had (c) significant drop of SBP and (d) less HR elevation. Note: SVR: sympathetic vasomotor response; MSA: multiple system atrophy; HR: heart rate; SBP: systolic blood pressure.
