WebThe normal LVOT flow pattern is a laminar flow pattern during systole. The flow profile is a quick upstroke, followed by a smooth arc, which peaks in midsystole, and has a quick downstroke. The maximum velocity of the flow profile should peak at about 100 cm/sec or less. To measure the LVOT profile with PWD, the sample volume should be placed ...
