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
Catholic theology of the body dominating all subordinate material instincts, becomes similar to God. This similarity must be goal of all human undertaking. Gregory of Nazianzus (330-390) contemplated on the origin of the human body. Man was created by God with body and soul, a visible and invisible part, like the angels.
