Quiz
The PW Doppler can be used for
(Required)
Estimating maximal velocities along the LVOT and aortic root
Determining the flow pattern (laminar vs. turbulent)
Assessment of diastolic function without a concominant ECG recording

Baseline-Filter
Grayscale
Pulse repetition frequency
Adjustments of CW-Doppler influencing the achieved information do not include
