Left ventricular E-wave/A-wave by US

Active

Term Description

The E to A ratio using a TDI waveform instead of MV. Standard TDI diastology calculation.

Part Description

LP72502-5 E wave
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
