Part Descriptions
LP189366-0 US.tissue 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. In tissue doppler ultrasound, the same Doppler principles are used to quantify the higher-amplitude, lower-velocity signals of myocardial tissue motion. PMID: 16534017

LP191909-3 Tissue velocity.E wave.max
The e prime (e') wave (LOINC component: tissue velocity.E wave) represents the annular tissue velocity of the mitral or tricuspid valve during early diastole, before atrial contraction. The blood flow velocity during early diastole is known as the E wave (LOINC component: blood flow velocity.E wave). The early diastolic velocity ratio (E/e') is an indicator of left ventricular diastolic function. PMID: 20451803 The ratio of early diastolic tissue velocity to tissue velocity during atrial contraction (e'/a') may also be an indicator of left ventricular function but is less reliable than the E/e' ratio.
