Tissue Doppler echocardiography Tissue Doppler echocardiography Tissue Doppler echocardiography (TDE) is a medical ultrasound technology, specifically a form of echocardiography that measures the velocity of the heart muscle (myocardium) through the phases of one or more heartbeats by the Doppler effect (frequency shift) of the reflected ultrasound. The technique is the same as for flow Doppler echocardiography measuring flow velocities. Tissue signals, however, have higher amplitude and lower velocities, and the signals are extracted by using different filter and gain settings. The terms tissue Doppler imaging (TDI) and tissue velocity imaging (TVI) are usually synonymous with TDE because echocardiography is the main use
The Tale of the Body Thief again so that she wouldn't lose him. This could make "Tale of the Body Thief" the second of two "Vampire Chronicle" novels inspired by Rice's personal tragedies, the first being "Interview with the Vampire" (which is denied by Rice). Lestat's adjustment to his human body takes up a major portion of the book—after almost two centuries of being a vampire, he finds he has trouble with the basic human nuances of eating, defecating, and taking care of his body. One of the realizations made by Lestat is that he took his powers for granted for too long; only after his
