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

LP203319-1 Dyssynchrony index.systole
Left ventricular (LV) systolic dyssynchrony represents variability in the timing of contraction in different LV myocardial segments. The mechanical dyssynchrony index, also
known as the Yu index, is one measure of systolic dyssynchrony and is calculated based on the standard deviation of the time to peak systolic velocity for each segment as measured by echo. LV dyssynchrony leads to decreased pumping efficiency and therefore a decrease in the LV ejection fraction, and is significantly correlated with LV systolic dysfunction in patients with heart failure independent of myocardial perfusion.
