Part Descriptions

LP76206-9   E wave.max
The E wave represents the flow of blood through the mitral or tricuspid valve into the ventricle (ventricular filling) during early diastole, before atrial contraction (LOINC component: blood flow velocity.E wave). [PMID: 20451803] Source: DICOM, PMID: 20451803

LP6617-7   US.doppler
Doppler ultrasound detects the shift in frequency of ultrasound signals reflected from moving objects. Conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low-amplitude signals from small, fast-moving blood cells.
