Abstrakt		Tissue Doppler echocardiography is a modification of the conventional colour Doppler technology, which is used for the measurement of cardiac tissue velocities. Tissue velocities are considerably lower, but with the amplitudes which are much higher than those recorded from blood flow. Tissue Doppler echocardiography has the potential to assess the contractions and relaxations of the left and right ventricles, the rate of myocardial thickening, and transmural velocity gradients, and can also be used to measure systolic and diastolic time intervals on a regional basis. Its clinical utility in these and other less frequent indications has yet to be confirmed.
Izvleček		Tkivna doplerska ehokardiografija je prilagojena doplerska preiskava, ki omogoča merjenje hitrosti in smeri gibanja miokarda. Z metodo registriramo doplerske odboje z relativno majhno hitrostjo in veliko amplitudo, ki izvirajo iz miokarda. Z metodo tkivne doplerske ehokardiografije lahko opazujemo krčenje in relaksacijo levega in desnega prekata, hitrost zadebelitve sten, tkivne gradiente hitrosti, merimo regionalne sistolične in diastolične časovne intervale. Klinična uporabnost metode za boljšo globalno in regionalno oceno funkcije srca in uporabnost v nekaterih redkejših indikacijah še ni dorečena.
