Introduction: Asynchrony indexes derived from tissue velocity imaging (TVI) have been reported to predict left ventricular reverse remodeling after cardiac resynchronization therapy (CRT). The predictive characteristics of these indices have not been validated in a variety of practice settings. Further, ...
Imagine a car driving down the street: As it approaches, the sound made by its engine gains in pitch, once it passes by, the sound of the engine lowers in pitch. This is called the Doppler effect. The same principle can be applied to measure ocean currents with an Acoustic Doppler Curre...
